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).
Writing code for Python 2 and 3¶
IPython 6 requires Python 3, so our compatibility module
IPython.utils.py3compat is deprecated and will be removed in a future
version. In most cases, we recommend you use the six module to support compatible code. This is widely
used by other projects, so it is familiar to many developers and thoroughly
py3compat module provided some more specific unicode conversions than
those offered by
six. If you want to use these, copy them into your own code
from IPython 5.x. Do not rely on importing them from IPython, as the module may
be removed in the future.
