Porting Extension Modules to Python 3

We recommend the following resources for porting extension modules to Python 3:

  • The Migrating C extensions_ chapter from Supporting Python 3: An in-depth guide, a book on moving from Python 2 to Python 3 in general, guides the reader through porting an extension module.
  • The Porting guide_ from the py3c project provides opinionated suggestions with supporting code.
  • :ref:Recommended third party tools <c-api-tools> offer abstractions over the 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.
