This documentation covers a development version of IPython. The development version may differ significantly from the latest stable release.
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).
Utilities for working with data structures like lists, dicts and tuples.
uniq_stable(elems) → list¶
Return from an iterable, a list of all the unique elements in the input, but maintaining the order in which they first appear.
Note: All elements in the input must be hashable for this routine to work, as it internally uses a set for efficiency reasons.
Flatten a list of lists (NOT recursive, only works for 2d lists).
Chop a sequence into chunks of the given size.
