How to port Python 2 Code to Python 3
*************************************

:author: Brett Cannon

Python 2 reached its official end-of-life at the start of 2020. This means
that no new bug reports, fixes, or changes will be made to Python 2 - it's
no longer supported: see :pep:`373` and
`status of Python versions <https://devguide.python.org/versions>`_.

If you are looking to port an extension module instead of pure Python code,
please see :ref:`cporting-howto`.

The archived python-porting_ mailing list may contain some useful guidance.

Since Python 3.11 the original porting guide was discontinued.
You can find the old guide in the
`archive <https://docs.python.org/3.10/howto/pyporting.html>`_.
