<p>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 <span class="target" id="index-0"></span><a class="pep reference external" href="https://peps.python.org/pep-0373/"><strong>PEP 373</strong></a> and
|
||
<a class="reference external" href="https://devguide.python.org/versions">status of Python versions</a>.</p>
|
||
<p>If you are looking to port an extension module instead of pure Python code,
|
||
please see <a class="reference internal" href="cporting.html#cporting-howto"><span class="std std-ref">Porting Extension Modules to Python 3</span></a>.</p>
|
||
<p>The archived <a class="reference external" href="https://mail.python.org/pipermail/python-porting/">python-porting</a> mailing list may contain some useful guidance.</p>
|
||
<p>Since Python 3.11 the original porting guide was discontinued.
|
||
You can find the old guide in the
|
||
<a class="reference external" href="https://docs.python.org/3.10/howto/pyporting.html">archive</a>.</p>
