| At the bottom of this page, you will find various resources for diving more into aspects of supporting Python 3, from the pure-Python, C extension module, Debian packaging, and other perspectives.

Q/A
- Why not rely on 2to3? 2to3 is a pretty slow tool so it can impede on the speed with which you develop your code. It can however be used in non-overwrite mode to get a good sense of what needs to be changed in your source code. Generally, a single-source approach is the best for bilingual (i.e. Py2 and Py3) Python apps.
