Porting code to Python 3
Since Python 3 introduces some incompatibilities, a porting strategy is needed to be able to run code on Python 3, and to have a single codebase that can be made to work under Python 2 and Python 3 using automatic conversion.
There are two separate issues here:
When finished, these two documents are meant to be a comprehensive guide to porting and maintaining Python 2/3 code. They are authored here in the Wiki and will be included in the official Python documentation when in a good shape.
We also have a Quick Reference to porting code to run on both python2 and python3. At some point, this should be folded into the above pages but currently it contains a quick reference for both Python code and extension modules so it needs some restructuring to fit in.
Porting Coordination
A few people from various Linux distributions are interested in starting a central point to work on porting to python3. Starting to organize this here: PortingToPy3k/PortingHelpers
Contact
Help with and discussion of porting is available on the python-porting mailing list.
