 <span id="cporting-howto"></span><h1>Porting Extension Modules to Python 3</h1> <p>We recommend the following resources for porting extension modules to Python 3:</p> <ul class="simple"> <li>The <a class="reference external" href="http://python3porting.com/cextensions.html">Migrating C extensions</a> chapter from <em>Supporting Python 3: An in-depth guide</em>, a book on moving from Python 2 to Python 3 in general, guides the reader through porting an extension module.</li> <li>The <a class="reference external" href="https://py3c.readthedocs.io/en/latest/guide.html">Porting guide</a> from the <em>py3c</em> project provides opinionated suggestions with supporting code.</li> <li>The <a class="reference external" href="https://cython.org/">Cython</a> and <a class="reference external" href="https://cffi.readthedocs.io/en/latest/">CFFI</a> libraries offer abstractions over Python’s C API. Extensions generally need to be re-written to use one of them, but the library then handles differences between various Python versions and implementations.</li> </ul> <div class="_attribution">
