Warning

This documentation covers a development version of IPython. The development version may differ significantly from the latest stable release.

Important

This documentation covers IPython versions 6.0 and higher. Beginning with version 6.0, IPython stopped supporting compatibility with Python versions lower than 3.3 including all versions of Python 2.7.

If you are looking for an IPython version compatible with Python 2.7, please use the IPython 5.x LTS release and refer to its documentation (LTS is the long term support release).

7.x Series¶

IPython 7.34¶

This version contains a single fix: fix uncaught BdbQuit exceptions on ipdb exit PR #13668

IPython 7.33¶

Allow IPython hooks to receive current cell ids when frontend support it. See PR #13600

? does not trigger the insertion of a new cell anymore as most frontend allow proper multiline edition. PR #13625

IPython 7.32¶

Autoload magic lazily¶

The ability to configure magics to be lazily loaded has been added to IPython. See the ipython --help-all section on MagicsManager.lazy_magic. One can now use:

c.MagicsManager.lazy_magics = {
          "my_magic": "slow.to.import",
          "my_other_magic": "also.slow",
}

And on first use of %my_magic, or corresponding cell magic, or other line magic, the corresponding load_ext will be called just before trying to invoke the magic.

Misc¶

Update sphinxify for Docrepr 0.2.0 PR #13503.

Set co_name for cells run line by line (to fix debugging with Python 3.10) PR #13535

Many thanks to all the contributors to this release. You can find all individual contributions to this milestone on github.

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.31¶

IPython 7.31 brings a couple of backports and fixes from the 8.0 branches, it is likely one of the last releases of the 7.x series, as 8.0 will probably be released between this release and what would have been 7.32.

Please test 8.0 beta/rc releases in addition to this release.

This Releases:

Backport some fixes for Python 3.10 (PR #13412)
use full-alpha transparency on dvipng rendered LaTeX (PR #13372)

Many thanks to all the contributors to this release. You can find all individual contributions to this milestone on github.

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.30¶

IPython 7.30 fixes a couple of bugs introduce in previous releases (in particular with respect to path handling), and introduce a few features and improvements:

Notably we will highlight PR #13267 “Document that %run can execute notebooks and ipy scripts.”, which is the first commit of Fernando Pérez since mid 2016 (IPython 5.1). If you are new to IPython, Fernando created IPython in 2001. The other most recent contribution of Fernando to IPython itself was May 2018, by reviewing and merging PRs. I want to note that Fernando is still active but mostly as a mentor and leader of the whole Jupyter organisation, but we’re still happy to see him contribute code !

PR #13290 “Use sphinxify (if available) in object_inspect_mime path” should allow richer Repr of docstrings when using jupyterlab inspector.

PR #13311 make the debugger use ThreadPoolExecutor for debugger cmdloop. This should fix some issues/infinite loop, but let us know if you come across any regressions. In particular this fixes issues with kmaork/madbg, a remote debugger for IPython.

Note that this is likely the ante-penultimate release of IPython 7.x as a stable branch, as I hope to release IPython 8.0 as well as IPython 7.31 next month/early 2022.

IPython 8.0 will drop support for Python 3.7, removed nose as a dependency, and 7.x will only get critical bug fixes with 8.x becoming the new stable. This will not be possible without NumFOCUS Small Development Grants Which allowed us to hire Nikita Kniazev who provide Python and C++ help and contracting work.

Many thanks to all the contributors to this release. You can find all individual contributions to this milestone on github.

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.29¶

IPython 7.29 brings a couple of new functionalities to IPython and a number of bugfixes. It is one of the largest recent release, relatively speaking, with close to 15 Pull Requests.

fix an issue where base64 was returned instead of bytes when showing figures PR #13162

fix compatibility with PyQt6, PySide 6 PR #13172. This may be of interest if you are running on Apple Silicon as only qt6.2+ is natively compatible.

fix matplotlib qtagg eventloop PR #13179

Multiple docs fixes, typos, … etc.

Debugger will now exit by default on SigInt PR #13218, this will be useful in notebook/lab if you forgot to exit the debugger. “Interrupt Kernel” will now exist the debugger.

It give Pdb the ability to skip code in decorators. If functions contain a special value names __debuggerskip__ = True|False, the function will not be stepped into, and Pdb will step into lower frames only if the value is set to False. The exact behavior is still likely to have corner cases and will be refined in subsequent releases. Feedback welcome. See the debugger module documentation for more info. Thanks to the D. E. Shaw group for funding this feature.

The main branch of IPython is receiving a number of changes as we received a NumFOCUS SDG ($4800), to help us finish replacing nose by pytest, and make IPython future proof with an 8.0 release.

Many thanks to all the contributors to this release. You can find all individual contributions to this milestone on github.

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.28¶

IPython 7.28 is again a minor release that mostly bring bugfixes, and couple of improvement. Many thanks to MrMino, who again did all the work this month, and made a number of documentation improvements.

Here is a non-exhaustive list of changes,

Fixes:

async with doesn’t allow newlines PR #13090

Dynamically changing to vi mode via %config magic) PR #13091

Virtualenv handling fixes:

init_virtualenv now uses Pathlib PR #12548

Fix Improper path comparison of virtualenv directories PR #13140

Fix virtual environment user warning for lower case pathes PR #13094

Adapt to all sorts of drive names for cygwin PR #13153

New Features:

enable autoplay in embed YouTube player PR #13133

Documentation:

Fix formatting for the core.interactiveshell documentation PR #13118

Fix broken ipyparallel’s refs PR #13138

Improve formatting of %time documentation PR #13125

Reword the YouTubeVideo autoplay WN PR #13147

Highlighted features¶

`YouTubeVideo` autoplay and the ability to add extra attributes to `IFrame`¶

You can add any extra attributes to the <iframe> tag using the new extras argument in the IFrame class. For example:

In [1]: from IPython.display import IFrame

In [2]: IFrame(src="src", width=300, height=300, extras=['loading="eager"'])

The above cells will result in the following HTML code being displayed in a notebook:

<iframe
    width="300"
    height="300"
    src="src"
    frameborder="0"
    allowfullscreen
    loading="eager"
></iframe>

Related to the above, the YouTubeVideo class now takes an allow_autoplay flag, which sets up the iframe of the embedded YouTube video such that it allows autoplay.

Note

Whether this works depends on the autoplay policy of the browser rendering the HTML allowing it. It also could get blocked by some browser extensions.

Try it out!

In [1]: from IPython.display import YouTubeVideo

In [2]: YouTubeVideo("dQw4w9WgXcQ", allow_autoplay=True)

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.26¶

IPython 7.26 is a minor release that fixes a couple of issues, updates in API and Copyright/Licenses issues around various part of the codebase.

We’ll highlight this issue <https://github.com/ipython/ipython/issues/13039> pointing out we were including and refereeing to code from Stack Overflow which was CC-BY-SA, hence incompatible with the BSD license of IPython. This lead us to a rewriting of the corresponding logic which in our case was done in a more efficient way (in our case we were searching string prefixes instead of full strings).

You will notice also a number of documentation improvements and cleanup.

Of particular interest are the following Pull-requests:

The IPython directive now uses Sphinx logging for warnings. PR #13030.

Add expiry days option to pastebin magic and change http protocol to https. PR #13056

Make Ipython.utils.timing work with jupyterlite PR #13050.

Pastebin magic expiry days option¶

The Pastebin magic now has -e option to determine the number of days for paste expiration. For example the paste that created with %pastebin -e 20 1 magic will be available for next 20 days.

Thanks¶

Many thanks to all the contributors to this release and in particular MrMino who is doing most of the work those days. You can find all individual contributions to this milestone on github.

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.25¶

IPython 7.25 is a minor release that contains a single bugfix, which is highly recommended for all users of ipdb, ipython debugger %debug magic and similar.

Issuing commands like where from within the debugger would reset the local variables changes made by the user. It is interesting to look at the root cause of the issue as accessing an attribute (frame.f_locals) would trigger this side effects.

Thanks in particular to the patience from the reporters at D.E. Shaw for their initial bug report that was due to a similar coding oversight in an extension, and who took time to debug and narrow down the problem.

Thanks¶

Many thanks to all the contributors to this release you can find all individual contributions to this milestone on github.

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.24¶

Third release of IPython for 2021, mostly containing bug fixes. A couple of not typical updates:

Misc¶

Fix an issue where %recall would both succeeded and print an error message it failed. PR #12952

Drop support for NumPy 1.16 – practically has no effect beyond indicating in package metadata that we do not support it. PR #12937

Debugger improvements¶

The debugger (and %debug magic) have been improved and can skip or hide frames originating from files that are not writable to the user, as these are less likely to be the source of errors, or be part of system files this can be a useful addition when debugging long errors.

In addition to the global skip_hidden True|False command, the debugger has gained finer grained control of predicates as to whether to a frame should be considered hidden. So far 3 predicates are available :

tbhide: frames containing the local variable __tracebackhide__ set to True.

readonly: frames originating from readonly files, set to False.

ipython_internal: frames that are likely to be from IPython internal code, set to True.

You can toggle individual predicates during a session with

ipdb> skip_predicates readonly True

Read-only files will now be considered hidden frames.

You can call skip_predicates without arguments to see the states of current predicates:

ipdb> skip_predicates
current predicates:
    tbhide : True
    readonly : False
    ipython_internal : True

If all predicates are set to False, skip_hidden will practically have no effect. We attempt to warn you when all predicates are False.

Note that the readonly predicate may increase disk access as we check for file access permission for all frames on many command invocation, but is usually cached by operating systems. Let us know if you encounter any issues.

As the IPython debugger does not use the traitlets infrastructure for configuration, by editing your .pdbrc files and appending commands you would like to be executed just before entering the interactive prompt. For example:

# file : ~/.pdbrc
skip_predicates readonly True
skip_predicates tbhide False

Will hide read only frames by default and show frames marked with __tracebackhide__.

Thanks¶

Many thanks to all the contributors to this release you can find all individual contributions to this milestone on github.

Thanks as well to the D. E. Shaw group for sponsoring work on IPython and related libraries, in particular above mentioned improvements to the debugger.

IPython 7.23 and 7.23.1¶

Third release of IPython for 2021, mostly containing bug fixes. A couple of not typical updates:

We moved to GitHub actions away from Travis-CI, the transition may not be 100% complete (not testing on nightly anymore), but as we ran out of Travis-Ci hours on the IPython organisation that was a necessary step. PR #12900.

We have a new dependency: matplotlib-inline, which try to extract matplotlib inline backend specific behavior. It is available on PyPI and conda-forge thus should not be a problem to upgrade to this version. If you are a package maintainer that might be an extra dependency to package first. PR #12817 (IPython 7.23.1 fix a typo that made this change fail)

In the addition/new feature category, display() now have a clear=True option to clear the display if any further outputs arrives, allowing users to avoid having to use clear_output() directly. PR #12823.

In bug fixes category, this release fix an issue when printing tracebacks containing Unicode characters PR #12758.

In code cleanup category PR #12932 remove usage of some deprecated functionality for compatibility with Python 3.10.

Thanks¶

Many thanks to all the contributors to this release you can find all individual contributions to this milestone on github. In particular MrMino for responding to almost all new issues, and triaging many of the old ones, as well as takluyver, minrk, willingc for reacting quikly when we ran out of CI Hours.

Thanks as well to organisations, QuantStack (martinRenou and SylvainCorlay) for extracting matplotlib inline backend into its own package, and the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.22¶

Second release of IPython for 2021, mostly containing bug fixes. Here is a quick rundown of the few changes.

Fix some sys.excepthook shenanigan when embedding with qt, recommended if you – for example – use napari. PR #12842.
Fix bug when using the new ipdb %context magic PR #12844
Couples of deprecation cleanup PR #12868
Update for new dpast.com api if you use the %pastbin magic. PR #12712
Remove support for numpy before 1.16. PR #12836

Thanks¶

We have a new team member that you should see more often on the IPython repository, Błażej Michalik (@MrMino) have been doing regular contributions to IPython, and spent time replying to many issues and guiding new users to the codebase; they now have triage permissions to the IPython repository and we’ll work toward giving them more permission in the future.

Many thanks to all the contributors to this release you can find all individual contributions to this milestone on github.

Thanks as well to organisations, QuantStack for working on debugger compatibility for Xeus_python, and the D. E. Shaw group for sponsoring work on IPython and related libraries.

IPython 7.21¶

IPython 7.21 is the first release we have back on schedule of one release every month; it contains a number of minor fixes and improvements, notably, the new context command for ipdb

New “context” command in ipdb¶

It is now possible to change the number of lines shown in the backtrace information in ipdb using “context” command. PR #12826

(thanks @MrMino, there are other improvement from them on master).

Other notable changes in IPython 7.21¶

Fix some issues on new osx-arm64 PR #12804, PR #12807.
Compatibility with Xeus-Python for debugger protocol, PR #12809
Misc docs fixes for compatibility and uniformity with Numpydoc. PR #12824

Thanks¶

Many thanks to all the contributors to this release you can find all individual contribution to this milestone on github.

IPython 7.20¶

IPython 7.20 is the accumulation of 3 month of work on IPython, spacing between IPython release have been increased from the usual once a month for various reason.

Mainly as I’m too busy and the effectively sole maintainer, and

Second because not much changes happened before mid December.

The main driver for this release was the new version of Jedi 0.18 breaking API; which was taken care of in the master branch early in 2020 but not in 7.x as I though that by now 8.0 would be out.

The inclusion of a resolver in pip did not help and actually made things worse. If usually I would have simply pinned Jedi to <0.18; this is not a solution anymore as now pip is free to install Jedi 0.18, and downgrade IPython.

I’ll do my best to keep the regular release, but as the 8.0-dev branch and 7.x are starting to diverge this is becoming difficult in particular with my limited time, so if you have any cycles to spare I’ll appreciate your help to respond to issues and pushing 8.0 forward.

Here are thus some of the changes for IPython 7.20.

Support for PyQt5 >= 5.11 PR #12715

%reset remove imports more agressively PR #12718

fix the %conda magic PR #12739

compatibility with Jedi 0.18, and bump minimum Jedi version. PR #12793

IPython 7.19¶

IPython 7.19 accumulative two month of works, bug fixes and improvements, there was exceptionally no release last month.

Fix to restore the ability to specify more than one extension using command line flags when using traitlets 5.0 PR #12543

Docs docs formatting that make the install commands work on zsh PR #12587

Always display the last frame in tracebacks even if hidden with __tracebackhide__ PR #12601

Avoid an issue where a callback can be registered multiple times. PR #12625

Avoid an issue in debugger mode where frames changes could be lost. PR #12627

Never hide the frames that invoke a debugger, even if marked as hidden by __tracebackhide__ PR #12631

Fix calling the debugger in a recursive manner PR #12659

A number of code changes have landed on master and we are getting close to enough new features and codebase improvement that a 8.0 start to make sens. For downstream packages, please start working on migrating downstream testing away from iptest and using pytest, as nose will not work on Python 3.10 and we will likely start removing it as a dependency for testing.

IPython 7.18¶

IPython 7.18 is a minor release that mostly contains bugfixes.

CRLF is now handled by magics my default; solving some issues due to copy pasting on windows. PR #12475

Requiring pexpect >=4.3 as we are Python 3.7+ only and earlier version of pexpect will be incompatible. PR #12510

Minimum jedi version is now 0.16. PR #12488

IPython 7.17¶

IPython 7.17 brings a couple of new improvements to API and a couple of user facing changes to make the terminal experience more user friendly.

PR #12407 introduces the ability to pass extra argument to the IPython debugger class; this is to help a new project from kmaork (https://github.com/kmaork/madbg) to feature a fully remote debugger.

PR #12410 finally remove support for 3.6, while the codebase is still technically compatible; IPython will not install on Python 3.6.

lots of work on the debugger and hidden frames from @impact27 in PR #12437, PR #12445, PR #12460 and in particular PR #12453 which make the debug magic more robust at handling spaces.

Biggest API addition is code transformation which is done before code execution; IPython allows a number of hooks to catch non-valid Python syntax (magic, prompt stripping…etc). Transformers are usually called many time; typically:

When trying to figure out whether the code is complete and valid (should we insert a new line or execute ?)

During actual code execution pass before giving the code to Python’s exec.

This lead to issues when transformer might have had side effects; or do external queries. Starting with IPython 7.17 you can expect your transformer to be called less time.

Input transformers are now called only once in the execution path of InteractiveShell, allowing to register transformer that potentially have side effects (note that this is not recommended). Internal methods should_run_async, and run_cell_async now take a recommended optional transformed_cell, and preprocessing_exc_tuple parameters that will become mandatory at some point in the future; that is to say cells need to be explicitly transformed to be valid Python syntax ahead of trying to run them. PR #12440;

input_transformers can now also have an attribute has_side_effects set to True, when this attribute is present; this will prevent the transformers from being ran when IPython is trying to guess whether the user input is complete. Note that this may means you will need to explicitly execute in some case where your transformations are now not ran; but will not affect users with no custom extensions.

API Changes¶

Change of API and exposed objects automatically detected using frappuccino

The following items are new since 7.16.0:

+ IPython.core.interactiveshell.InteractiveShell.get_local_scope(self, stack_depth)

The following signatures differ since 7.16.0:

- IPython.core.interactiveshell.InteractiveShell.run_cell_async(self, raw_cell, store_history=False, silent=False, shell_futures=True)
+ IPython.core.interactiveshell.InteractiveShell.run_cell_async(self, raw_cell, store_history=False, silent=False, shell_futures=True, *, transformed_cell=None, preprocessing_exc_tuple=None)

- IPython.core.interactiveshell.InteractiveShell.should_run_async(self, raw_cell)
+ IPython.core.interactiveshell.InteractiveShell.should_run_async(self, raw_cell, *, transformed_cell=None, preprocessing_exc_tuple=None)

- IPython.terminal.debugger.TerminalPdb.pt_init(self)
+ IPython.terminal.debugger.TerminalPdb.pt_init(self, pt_session_options=None)

This method was added:

+ IPython.core.interactiveshell.InteractiveShell.get_local_scope

Which is now also present on subclasses:

+ IPython.terminal.embed.InteractiveShellEmbed.get_local_scope
+ IPython.terminal.interactiveshell.TerminalInteractiveShell.get_local_scope

IPython 7.16.1, 7.16.2¶

IPython 7.16.1 was release immediately after 7.16.0 to fix a conda packaging issue. The source is identical to 7.16.0 but the file permissions in the tar are different.

IPython 7.16.2 pins jedi dependency to “<=0.17.2” which should prevent some issues for users still on python 3.6. This may not be sufficient as pip may still allow to downgrade IPython.

Compatibility with Jedi > 0.17.2 was not added as this would have meant bumping the minimal version to >0.16.

IPython 7.16¶

The default traceback mode will now skip frames that are marked with __tracebackhide__ = True and show how many traceback frames have been skipped. This can be toggled by using %xmode with the --show or --hide attribute. It will have no effect on non verbose traceback modes.

The ipython debugger also now understands __tracebackhide__ as well and will skip hidden frames when displaying. Movement up and down the stack will skip the hidden frames and will show how many frames were hidden. Internal IPython frames are also now hidden by default. The behavior can be changed with the skip_hidden while in the debugger, command and accepts “yes”, “no”, “true” and “false” case insensitive parameters.

Misc Noticeable changes:¶

Exceptions are now (re)raised when running notebooks via the %run, helping to catch issues in workflows and pipelines. PR #12301
Fix inputhook for qt 5.15.0 PR #12355
Fix wx inputhook PR #12375
Add handling for malformed pathext env var (Windows) PR #12367
use $SHELL in system_piped PR #12360 for uniform behavior with ipykernel.

Reproducible Build¶

IPython 7.15 reproducible build did not work, so we try again this month PR #12358.

API Changes¶

Change of API and exposed objects automatically detected using frappuccino (still in beta):

The following items are new and mostly related to understanding __tracebackhide__:

+ IPython.core.debugger.Pdb.do_down(self, arg)
+ IPython.core.debugger.Pdb.do_skip_hidden(self, arg)
+ IPython.core.debugger.Pdb.do_up(self, arg)
+ IPython.core.debugger.Pdb.hidden_frames(self, stack)
+ IPython.core.debugger.Pdb.stop_here(self, frame)

The following items have been removed:

- IPython.core.debugger.Pdb.new_do_down
- IPython.core.debugger.Pdb.new_do_up

Those were implementation details.

IPython 7.15¶

IPython 7.15 brings a number of bug fixes and user facing improvements.

Misc Noticeable changes:¶

Long completion name have better elision in terminal PR #12284

I’ve started to test on Python 3.9 PR #12307 and fix some errors.

Hi DPI scaling of figures when using qt eventloop PR #12314

Document the ability to have systemwide configuration for IPython. PR #12328

Fix issues with input autoformatting PR #12336

IPython.core.debugger.Pdb is now interruptible (PR #12168, in 7.14 but forgotten in release notes)

Video HTML attributes (PR #12212, in 7.14 but forgotten in release notes)

Reproducible Build¶

Starting with IPython 7.15, I am attempting to provide reproducible builds, that is to say you should be able from the source tree to generate an sdist and wheel that are identical byte for byte with the publish version on PyPI.

I’ve only tested on a couple of machines so far and the process is relatively straightforward, so this mean that IPython not only have a deterministic build process, but also I have either removed, or put under control all effects of the build environments on the final artifact. I encourage you to attempt the build process on your machine as documented in Guide for IPython core Developers and let me know if you do not obtain an identical artifact.

While reproducible builds is critical to check that the supply chain of (open source) software has not been compromised, it can also help to speedup many of the build processes in large environment (conda, apt…) by allowing better caching of intermediate build steps.

Learn more on https://reproducible-builds.org/. Reflections on trusting trust is also one of the cornerstone and recommended reads on this subject.

Note

The build commit from which the sdist is generated is also signed, so you should be able to check it has not been compromised, and the git repository is a merkle-tree, you can check the consistency with git-fsck which you likely want to enable by default.

NEP29: Last version to support Python 3.6¶

IPython 7.15 will be the Last IPython version to officially support Python 3.6, as stated by NumPy Enhancement Proposal 29. Starting with next minor version of IPython I may stop testing on Python 3.6 and may stop publishing release artifacts that install on Python 3.6

Highlighted features¶

Highlighted features are not new, but seem to not be widely known, this section will help you discover in more narrative form what you can do with IPython.

Autoformat Code in the terminal¶

If you have a preferred code formatter, you can configure IPython to reformat your code. Set the value of TerminalInteractiveShell.autoformatter to for example 'black' and IPython will auto format your code when possible.

IPython 7.14¶

IPython 7.14 is a minor release that fix a couple of bugs and prepare compatibility with new or future versions of some libraries.

Important changes:¶

Fix compatibility with Sphinx 3+ PR #12235

Remove deprecated matplotlib parameter usage, compatibility with matplotlib 3.3+ :122250

Misc Changes¶

set .py extension when editing current buffer in vi/emacs. PR #12167

support for unicode identifiers in ?/?? PR #12208

add extra options to the Video Rich objects PR #12212

add pretty-printing to SimpleNamespace PR #12230

IPython.core.debugger.Pdb is now interruptible¶

A KeyboardInterrupt will now interrupt IPython’s extended debugger, in order to make Jupyter able to interrupt it. (PR #12168)

Video HTML attributes¶

Add an option to IPython.display.Video to change the attributes of the HTML display of the video (PR #12212)

Pending deprecated imports¶

Many object present in IPython.core.display are there for internal use only, and should already been imported from IPython.display by users and external libraries. Trying to import those from IPython.core.display is still possible but will trigger a deprecation warning in later versions of IPython and will become errors in the future.

This will simplify compatibility with other Python kernels (like Xeus-Python), and simplify code base.

IPython 7.13¶

IPython 7.13 is the final release of the 7.x branch since master is diverging toward an 8.0. Exiting new features have already been merged in 8.0 and will not be available on the 7.x branch. All the changes below have been backported from the master branch.

Fix inability to run PDB when inside an event loop PR #12141

Fix ability to interrupt some processes on windows PR #12137

Fix debugger shortcuts PR #12132

improve tab completion when inside a string by removing irrelevant elements PR #12128

Fix display of filename tab completion when the path is long PR #12122

Many removal of Python 2 specific code path PR #12110

displaying wav files do not require NumPy anymore, and is 5x to 30x faster PR #12113

See the list of all closed issues and pull request on github.

IPython 7.12¶

IPython 7.12 is a minor update that mostly brings code cleanup, removal of longtime deprecated function and a couple update to documentation cleanup as well.

Notable changes are the following:

Exit non-zero when ipython is given a file path to run that doesn’t exist PR #12074

Test PR on ARM64 with Travis-CI PR #12073

Update CI to work with latest Pytest PR #12086

Add infrastructure to run ipykernel eventloop via trio PR #12097

Support git blame ignore revs PR #12091

IPython 7.11.1¶

A couple of deprecated functions (no-op) have been reintroduces in py3compat as Cython was still relying on them, and will be removed in a couple of versions.

IPython 7.11¶

IPython 7.11 received a couple of compatibility fixes and code cleanup.

A number of function in the py3compat have been removed; a number of types in the IPython code base are now non-ambiguous and now always unicode instead of Union[Unicode,bytes]; many of the relevant code path have thus been simplified/cleaned and types annotation added.

IPython support several verbosity level from exceptions. xmode plain now support chained exceptions. PR #11999

We are starting to remove shell=True in some usages of subprocess. While not directly a security issue (as IPython is made to run arbitrary code anyway) it is not good practice and we’d like to show the example. #12023. This discussion was started by @mschwager thanks to a new auditing tool they are working on with duo-labs (dlint).

Work around some bugs in Python 3.9 tokenizer PR #12057

IPython will now print its version after a crash. PR #11986

This is likely the last release from the 7.x series that will see new feature. The master branch will soon accept large code changes and thrilling new features; the 7.x branch will only start to accept critical bug fixes, and update dependencies.

IPython 7.10.2¶

IPython 7.10.2 fix a couple of extra incompatibility between IPython, ipdb, asyncio and Prompt Toolkit 3.

IPython 7.10.1¶

IPython 7.10.1 fix a couple of incompatibilities with Prompt toolkit 3 (please update Prompt toolkit to 3.0.2 at least), and fixes some interaction with headless IPython.

IPython 7.10.0¶

IPython 7.10 is the first double digit minor release in the last decade, and first since the release of IPython 1.0, previous double digit minor release was in August 2009.

We’ve been trying to give you regular release on the last Friday of every month for a guaranty of rapid access to bug fixes and new features.

Unlike the previous first few releases that have seen only a couple of code changes, 7.10 bring a number of changes, new features and bugfixes.

Stop Support for Python 3.5 – Adopt NEP 29¶

IPython has decided to follow the informational NEP 29 which layout a clear policy as to which version of (C)Python and NumPy are supported.

We thus dropped support for Python 3.5, and cleaned up a number of code path that were Python-version dependant. If you are on 3.5 or earlier pip should automatically give you the latest compatible version of IPython so you do not need to pin to a given version.

Support for Prompt Toolkit 3.0¶

Prompt Toolkit 3.0 was release a week before IPython 7.10 and introduces a few breaking changes. We believe IPython 7.10 should be compatible with both Prompt Toolkit 2.x and 3.x, though it has not been extensively tested with 3.x so please report any issues.

Prompt Rendering Performance improvements¶

Pull Request PR #11933 introduced an optimisation in the prompt rendering logic that should decrease the resource usage of IPython when using the _default_ configuration but could potentially introduce a regression of functionalities if you are using a custom prompt.

We know assume if you haven’t changed the default keybindings that the prompt will not change during the duration of your input – which is for example not true when using vi insert mode that switches between [ins] and [nor] for the current mode.

If you are experiencing any issue let us know.

Code autoformatting¶

The IPython terminal can now auto format your code just before entering a new line or executing a command. To do so use the --TerminalInteractiveShell.autoformatter option and set it to 'black'; if black is installed IPython will use black to format your code when possible.

IPython cannot always properly format your code; in particular it will auto formatting with black will only work if:

Your code does not contains magics or special python syntax.

There is no code after your cursor.

The Black API is also still in motion; so this may not work with all versions of black.

It should be possible to register custom formatter, though the API is till in flux.

Arbitrary Mimetypes Handing in Terminal (Aka inline images in terminal)¶

When using IPython terminal it is now possible to register function to handle arbitrary mimetypes. While rendering non-text based representation was possible in many jupyter frontend; it was not possible in terminal IPython, as usually terminal are limited to displaying text. As many terminal these days provide escape sequences to display non-text; bringing this loved feature to IPython CLI made a lot of sens. This functionality will not only allow inline images; but allow opening of external program; for example mplayer to “display” sound files.

So far only the hooks necessary for this are in place, but no default mime renderers added; so inline images will only be available via extensions. We will progressively enable these features by default in the next few releases, and contribution is welcomed.

We welcome any feedback on the API. See Mime Renderer Extensions for more informations.

This is originally based on work form in PR #10610 from @stephanh42 started over two years ago, and still a lot need to be done.

MISC¶

Completions can define their own ordering PR #11855

Enable Plotting in the same cell than the one that import matplotlib PR #11916

Allow to store and restore multiple variables at once PR #11930

You can see all pull-requests for this release.

API Changes¶

Change of API and exposed objects automatically detected using frappuccino (still in beta):

The following items are new in IPython 7.10:

+ IPython.terminal.shortcuts.reformat_text_before_cursor(buffer, document, shell)
+ IPython.terminal.interactiveshell.PTK3
+ IPython.terminal.interactiveshell.black_reformat_handler(text_before_cursor)
+ IPython.terminal.prompts.RichPromptDisplayHook.write_format_data(self, format_dict, md_dict='None')

The following items have been removed in 7.10:

- IPython.lib.pretty.DICT_IS_ORDERED

The following signatures differ between versions:

- IPython.extensions.storemagic.restore_aliases(ip)
+ IPython.extensions.storemagic.restore_aliases(ip, alias='None')

Special Thanks¶

IPython 7.9.0¶

IPython 7.9 is a small release with a couple of improvement and bug fixes.

Xterm terminal title should be restored on exit PR #11910

special variables _,``__``, ___ are not set anymore when cache size is 0 or less. PR #11877

Autoreload should have regained some speed by using a new heuristic logic to find all objects needing reload. This should avoid large objects traversal like pandas dataframes. PR #11876

Get ready for Python 4. PR #11874

%env Magic now has heuristic to hide potentially sensitive values PR #11896

This is a small release despite a number of Pull Request Pending that need to be reviewed/worked on. Many of the core developers have been busy outside of IPython/Jupyter and we thanks all contributor for their patience; we’ll work on these as soon as we have time.

IPython 7.8.0¶

IPython 7.8.0 contain a few bugfix and 2 new APIs:

Enable changing the font color for LaTeX rendering PR #11840

and Re-Expose some PDB API (see below)

Expose Pdb API¶

Expose the built-in pdb.Pdb API. Pdb constructor arguments are generically exposed, regardless of python version. Newly exposed arguments:

skip - Python 3.1+
nosiginnt - Python 3.2+
readrc - Python 3.6+

Try it out:

from IPython.terminal.debugger import TerminalPdb
pdb = TerminalPdb(skip=["skipthismodule"])

See PR #11840

IPython 7.7.0¶

IPython 7.7.0 contain multiple bug fixes and documentation updates; Here are a few of the outstanding issue fixed:

Fix a bug introduced in 7.6 where the %matplotlib magic would fail on previously acceptable arguments PR #11814.

Fix the manage location on freebsd PR #11808.

Fix error message about aliases after %reset call in ipykernel PR #11806

Fix Duplication completions in emacs PR #11803

We are planning to adopt NEP29 (still currently in draft) which may make this minor version of IPython the last one to support Python 3.5 and will make the code base more aggressive toward removing compatibility with older versions of Python.

GitHub now support to give only “Triage” permissions to users; if you’d like to help close stale issues and labels issues please reach to us with your GitHub Username and we’ll add you to the triage team. It is a great way to start contributing and a path toward getting commit rights.

IPython 7.6.1¶

IPython 7.6.1 contain a critical bugfix in the %timeit magic, which would crash on some inputs as a side effect of PR #11716. See PR #11812

IPython 7.6.0¶

IPython 7.6.0 contains a couple of bug fixes and number of small features additions as well as some compatibility with the current development version of Python 3.8.

Add a -l option to %psearch to list the available search types. PR #11672

Autoreload now update the types of reloaded objects; this for example allow pickling of reloaded objects. PR #11644

Fix a bug where %%time magic would suppress cell output. PR #11716

Prepare migration to pytest (instead of nose) for testing¶

Most of the work between 7.5 and 7.6 was to prepare the migration from our testing framework to pytest. Most of the test suite should now work by simply issuing pytest from the root of the repository.

The migration to pytest is just at its beginning. Many of our test still rely on IPython-specific plugins for nose using pytest (doctest using IPython syntax is one example of this where test appear as “passing”, while no code has been ran). Many test also need to be updated like yield-test to be properly parametrized tests.

Migration to pytest allowed me to discover a number of issues in our test suite; which was hiding a number of subtle issues – or not actually running some of the tests in our test suite – I have thus corrected many of those; like improperly closed resources; or used of deprecated features. I also made use of the pytest --durations=... to find some of our slowest test and speed them up (our test suite can now be up to 10% faster). Pytest as also a variety of plugins and flags which will make the code quality of IPython and the testing experience better.

Misc¶

We skipped the release of 7.6 at the end of May, but will attempt to get back on schedule. We are starting to think about making introducing backward incompatible change and start the 8.0 series.

Special Thanks to Gabriel (@gpotter2 on GitHub), who among other took care many of the remaining task for 7.4 and 7.5, like updating the website.

IPython 7.5.0¶

IPython 7.5.0 consist mostly of bug-fixes, and documentation updates, with one minor new feature. The Audio display element can now be assigned an element id when displayed in browser. See PR #11670

The major outstanding bug fix correct a change of behavior that was introduce in 7.4.0 where some cell magics would not be able to access or modify global scope when using the @needs_local_scope decorator. This was typically encountered with the %%time and %%timeit magics. See #11659 and PR #11698.

IPython 7.4.0¶

Unicode name completions¶

Previously, we provided completion for a unicode name with its relative symbol. With this, now IPython provides complete suggestions to unicode name symbols.

As on the PR, if user types \LAT<tab>, IPython provides a list of possible completions. In this case, it would be something like:

'LATIN CAPITAL LETTER A',
'LATIN CAPITAL LETTER B',
'LATIN CAPITAL LETTER C',
'LATIN CAPITAL LETTER D',
....

This help to type unicode character that do not have short latex aliases, and have long unicode names. for example Ͱ, \GREEK CAPITAL LETTER HETA.

This feature was contributed by Luciana Marques PR #11583.

Make audio normalization optional¶

Added ‘normalize’ argument to IPython.display.Audio. This argument applies when audio data is given as an array of samples. The default of normalize=True preserves prior behavior of normalizing the audio to the maximum possible range. Setting to False disables normalization.

Miscellaneous¶

Fix improper acceptation of return outside of functions. PR #11641.

Fixed PyQt 5.11 backwards incompatibility causing sip import failure. PR #11613.

Fix Bug where type? would crash IPython. PR #1608.

Allow to apply @needs_local_scope to cell magics for convenience. PR #11542.

IPython 7.3.0¶

IPython 7.3.0 bring several bug fixes and small improvements that you will described bellow.

The biggest change to this release is the implementation of the %conda and %pip magics, that will attempt to install packages in the current environment. You may still need to restart your interpreter or kernel for the change to be taken into account, but it should simplify installation of packages into remote environment. Installing using pip/conda from the command line is still the prefer method.

The %pip magic was already present, but was only printing a warning; now it will actually forward commands to pip.

Misc bug fixes and improvements:

Compatibility with Python 3.8.

Do not expand shell variable in execution magics, and added the no_var_expand decorator for magic requiring a similar functionality PR #11516

Add %pip and %conda magic PR #11524

Re-initialize posix aliases after a %reset PR #11528

Allow the IPython command line to run *.ipynb files PR #11529

IPython 7.2.0¶

IPython 7.2.0 brings minor bugfixes, improvements, and new configuration options:

Fix a bug preventing PySide2 GUI integration from working PR #11464

Run CI on Mac OS ! PR #11471

Fix IPython “Demo” mode. PR #11498

Fix %run magic with path in name PR #11499

Fix: add CWD to sys.path after stdlib PR #11502

Better rendering of signatures, especially long ones. PR #11505

Re-enable jedi by default if it’s installed PR #11506

Add New minimal exception reporting mode (useful for educational purpose). See PR #11509

Added ability to show subclasses when using pinfo and other utilities¶

When using ?/?? on a class, IPython will now list the first 10 subclasses.

Special Thanks to Chris Mentzel of the Moore Foundation for this feature. Chris is one of the people who played a critical role in IPython/Jupyter getting funding.

We are grateful for all the help Chris has given us over the years, and we’re now proud to have code contributed by Chris in IPython.

OSMagics.cd_force_quiet configuration option¶

You can set this option to force the %cd magic to behave as if -q was passed:

In [1]: cd /
/

In [2]: %config OSMagics.cd_force_quiet = True

In [3]: cd /tmp

In [4]:

See PR #11491

In vi editing mode, whether the prompt includes the current vi mode can now be configured¶

Set the TerminalInteractiveShell.prompt_includes_vi_mode to a boolean value (default: True) to control this feature. See PR #11492

IPython 7.1.0¶

IPython 7.1.0 is the first minor release after 7.0.0 and mostly brings fixes to new features, internal refactoring, and fixes for regressions that happened during the 6.x->7.x transition. It also brings Compatibility with Python 3.7.1, as we’re unwillingly relying on a bug in CPython.

New Core Dev:

We welcome Jonathan Slenders to the commiters. Jonathan has done a fantastic work on prompt_toolkit, and we’d like to recognise his impact by giving him commit rights. #11397

Notable Changes

Major update of “latex to unicode” tab completion map (see below)

Notable New Features:

Restore functionality and documentation of the sphinx directive, which is now stricter (fail on error by daefault), has new configuration options, has a brand new documentation page IPython Sphinx Directive (which needs some cleanup). It is also now tested so we hope to have less regressions. PR #11402

IPython.display.Video now supports width and height arguments, allowing a custom width and height to be set instead of using the video’s width and height. PR #11353

Warn when using HTML('<iframe>') instead of IFrame PR #11350

Allow Dynamic switching of editing mode between vi/emacs and show normal/input mode in prompt when using vi. PR #11390. Use %config TerminalInteractiveShell.editing_mode = 'vi' or %config TerminalInteractiveShell.editing_mode = 'emacs' to dynamically switch between modes.

Notable Fixes:

Fix entering of multi-line blocks in terminal IPython, and various crashes in the new input transformation machinery PR #11354, PR #11356, PR #11358. These also fix a Compatibility bug with Python 3.7.1.

Fix moving through generator stack in ipdb PR #11266

%Magic command arguments now support quoting. PR #11330

Re-add rprint and rprinte aliases. PR #11331

Remove implicit dependency on ipython_genutils PR #11317

Make nonlocal raise SyntaxError instead of silently failing in async mode. PR #11382

Fix mishandling of magics and = ! assignment just after a dedent in nested code blocks PR #11418

Fix instructions for custom shortcuts PR #11426

Notable Internals improvements:

Use of os.scandir (Python 3 only) to speed up some file system operations. PR #11365

use perf_counter instead of clock for more precise timing results with %time PR #11376

Many thanks to all the contributors and in particular to bartskowron and tonyfast who handled some pretty complicated bugs in the input machinery. We had a number of first time contributors and maybe hacktoberfest participants that made significant contributions and helped us free some time to focus on more complicated bugs.

You can see all the closed issues and Merged PR, new features and fixes here.

Unicode Completion update¶

In IPython 7.1 the Unicode completion map has been updated and synchronized with the Julia language.

Added and removed character characters:

\jmath (ȷ), \\underleftrightarrow (U+034D, combining) have been added, while \\textasciicaron have been removed

Some sequences have seen their prefix removed:

6 characters \text...<tab> should now be inputed with \...<tab> directly,

45 characters \Elz...<tab> should now be inputed with \...<tab> directly,

65 characters \B...<tab> should now be inputed with \...<tab> directly,

450 characters \m...<tab> should now be inputed with \...<tab> directly,

Some sequences have seen their prefix shortened:

5 characters \mitBbb...<tab> should now be inputed with \bbi...<tab> directly,

52 characters \mit...<tab> should now be inputed with \i...<tab> directly,

216 characters \mbfit...<tab> should now be inputed with \bi...<tab> directly,

222 characters \mbf...<tab> should now be inputed with \b...<tab> directly,

A couple of characters had their sequence simplified:

ð, type \dh<tab>, instead of \eth<tab>

ħ, type \hbar<tab>, instead of \Elzxh<tab>

ɸ, type \ltphi<tab>, instead of \textphi<tab>

ϴ, type \varTheta<tab>, instead of \textTheta<tab>

ℇ, type \eulermascheroni<tab>, instead of \Eulerconst<tab>

ℎ, type \planck<tab>, instead of \Planckconst<tab>

U+0336 (COMBINING LONG STROKE OVERLAY), type \strike<tab>, instead of \Elzbar<tab>.

A couple of sequences have been updated:

\varepsilon now gives ɛ (GREEK SMALL LETTER EPSILON) instead of ε (GREEK LUNATE EPSILON SYMBOL),

\underbar now gives U+0331 (COMBINING MACRON BELOW) instead of U+0332 (COMBINING LOW LINE).

IPython 7.0.0¶

Released Thursday September 27th, 2018

IPython 7 includes major feature improvements. This is also the second major version of IPython to support only Python 3 – starting at Python 3.4. Python 2 is still community-supported on the bugfix only 5.x branch, but we remind you that Python 2 “end of life” is on Jan 1st 2020.

We were able to backport bug fixes to the 5.x branch thanks to our backport bot which backported more than 70 Pull-Requests, but there are still many PRs that required manual work. This is an area of the project where you can easily contribute by looking for PRs that still need manual backport

The IPython 6.x branch will likely not see any further release unless critical bugs are found.

Make sure you have pip > 9.0 before upgrading. You should be able to update by running:

pip install ipython --upgrade

If you are trying to install or update an alpha, beta, or rc version, use pip --pre flag.

pip install ipython --upgrade --pre

Or, if you have conda installed:

conda install ipython

Prompt Toolkit 2.0¶

IPython 7.0+ now uses prompt_toolkit 2.0. If you still need to use an earlier prompt_toolkit version, you may need to pin IPython to <7.0.

Autowait: Asynchronous REPL¶

Staring with IPython 7.0 on Python 3.6+, IPython can automatically await top level code. You should not need to access an event loop or runner yourself. To learn more, read the Asynchronous in REPL: Autoawait section of our docs, see PR #11265, or try the following code:

Python 3.6.0
Type 'copyright', 'credits' or 'license' for more information
IPython 7.0.0 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import aiohttp
   ...: result = aiohttp.get('https://api.github.com')

In [2]: response = await result
<pause for a few 100s ms>

In [3]: await response.json()
Out[3]:
{'authorizations_url': 'https://api.github.com/authorizations',
 'code_search_url': 'https://api.github.com/search/code?q={query}{&page,per_page,sort,order}',
...
}

Note

Async integration is experimental code, behavior may change or be removed between Python and IPython versions without warnings.

Integration is by default with asyncio, but other libraries can be configured – like curio or trio – to improve concurrency in the REPL:

In [1]: %autoawait trio

In [2]: import trio

In [3]: async def child(i):
   ...:     print("   child %s goes to sleep"%i)
   ...:     await trio.sleep(2)
   ...:     print("   child %s wakes up"%i)

In [4]: print('parent start')
   ...: async with trio.open_nursery() as n:
   ...:     for i in range(3):
   ...:         n.spawn(child, i)
   ...: print('parent end')
parent start
   child 2 goes to sleep
   child 0 goes to sleep
   child 1 goes to sleep
   <about 2 seconds pause>
   child 2 wakes up
   child 1 wakes up
   child 0 wakes up
parent end

See Asynchronous in REPL: Autoawait for more information.

Asynchronous code in a Notebook interface or any other frontend using the Jupyter Protocol will require further updates to the IPykernel package.

Non-Asynchronous code¶

As the internal API of IPython is now asynchronous, IPython needs to run under an event loop. In order to allow many workflows, (like using the %run magic, or copy-pasting code that explicitly starts/stop event loop), when top-level code is detected as not being asynchronous, IPython code is advanced via a pseudo-synchronous runner, and may not advance pending tasks.

Change to Nested Embed¶

The introduction of the ability to run async code had some effect on the IPython.embed() API. By default, embed will not allow you to run asynchronous code unless an event loop is specified.

Effects on Magics¶

Some magics will not work with async until they’re updated. Contributions welcome.

Expected Future changes¶

We expect more internal but public IPython functions to become async, and will likely end up having a persistent event loop while IPython is running.

Thanks¶

This release took more than a year in the making. The code was rebased a number of times; leading to commit authorship that may have been lost in the final Pull-Request. Huge thanks to many people for contribution, discussion, code, documentation, use-cases: dalejung, danielballan, ellisonbg, fperez, gnestor, minrk, njsmith, pganssle, tacaswell, takluyver , vidartf … And many others.

Autoreload Improvement¶

The magic %autoreload 2 now captures new methods added to classes. Earlier, only methods existing as of the initial import were being tracked and updated.

This new feature helps dual environment development - Jupyter+IDE - where the code gradually moves from notebook cells to package files as it gets structured.

Example: An instance of the class MyClass will be able to access the method cube() after it is uncommented and the file file1.py is saved on disk.

# notebook

from mymodule import MyClass
first = MyClass(5)

# mymodule/file1.py

class MyClass:

    def __init__(self, a=10):
        self.a = a

    def square(self):
        print('compute square')
        return self.a*self.a

    # def cube(self):
    #     print('compute cube')
    #     return self.a*self.a*self.a

Misc¶

The autoindent feature that was deprecated in 5.x was re-enabled and un-deprecated in PR #11257

Make %run -n -i ... work correctly. Earlier, if %run was passed both arguments, -n would be silently ignored. See PR #10308

The %%script (as well as %%bash, %%ruby… ) cell magics now raise by default if the return code of the given code is non-zero (thus halting execution of further cells in a notebook). The behavior can be disable by passing the --no-raise-error flag.

Deprecations¶

A couple of unused functions and methods have been deprecated and will be removed in future versions:

IPython.utils.io.raw_print_err

IPython.utils.io.raw_print

Backwards incompatible changes¶

The API for transforming input before it is parsed as Python code has been completely redesigned: any custom input transformations will need to be rewritten. See Custom input transformation for details of the new API.
