I myself consider these resources great: https://docs.python.org/dev/howto/pyporting.html (upstream docs on porting Python code) https://docs.python.org/3/howto/cporting.html (upstream docs on porting Python C extension) http://python3porting.com/ (a great reference for both C and Python porting, including tons of examples) http://www.wefearchange.org/2011/12/lessons-in-porting-to-python-3.html (a blogpost on how python-dbus was ported, lots of great gotchas there) http://lucumr.pocoo.org/2013/7/2/the-updated-guide-to-unicode/ (interesting notes on work with unicode) https://wiki.gnome.org/PyGObject/IntrospectionPorting (porting from PyGTK to PyGObject Introspection) http://overtag.dk/wordpress/2013/01/first-impressions-of-gtk3-migration-in-python/ (same as above) >From the tools/libraries that can be used: - https://docs.python.org/3.4/library/2to3.html (package python3-tools) is a tool that you run on your code in order to *move* it to Python 3 (e.g. doesn't guarantee backwards compat) - http://python-modernize.readthedocs.org/en/latest/ (package python-modernize) - like 2to3, but tries to maintain backwards compat with Python 2.6+ - https://pythonhosted.org/six/ (package python{,3}-six) - importable library that helps write code compatible with both Python 2 and 3 And you can also have a look at my presentation from this year's Flock, it speaks about basic differences, porting and how people can help with porting: https://bkabrda.fedorapeople.org/py3-as-default.pdf Hope this helps! > Best regards, > > -- > Michel Alexandre Salim > Fedora Project Contributor: http://fedoraproject.org/ > > Email: salimma@xxxxxxxxxxxxxxxxx | GPG key ID: A36A937A > IDs: keybase.io/michel-slm | IRC: michel_slm@xxxxxxxxxxxxxxxx > > () ascii ribbon campaign - against html e-mail > /\ www.asciiribbon.org - against proprietary attachments -- Regards, Slavek Kabrda -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
