Revision as of 20:50, 27 January 2012

A python 3 stack was added to Fedora in Fedora 13, parallel-installable with the "main" Python 2 stack, and it is gradually growing additional RPMs, as more code is ported to Python 3.

Note that /usr/bin/python is still Python 2.

Porting status

Please keep each of these tables sorted alphabetically by python module name

Python 3 already in Fedora

Please let us know if this information is out-of-date.

FIXME: add note about if a python3 version should be packaged

Python Module Fedora Python 2 package Upstream status of Python 3 Fedora Python 3 package
augeas python-augeas dmalcolm has experimented with porting this to python 3
Cheetah python-cheetah As of 2010-02-02, upstream site reports that Python 3.xx support will be in Cheetah v3.0, but that it is "still in planning"
cracklib cracklib-python Looking at cracklib-2.8.16, looks like the module needs some work to port (e.g. module initialization), and uses automake so may need work to build multiple times
dbus dbus-python Patch created by Fedora contributor John Palmieri sent upstream, awaiting upstream review - also GDBus can be used through pygobject introspection rhbz 538616
django Django http://wiki.python.org/moin/PortingDjangoTo3k - there's an experimental branch in bitbucket, but as of 2010-04-09 it doesn't appear to have "official" releases

Python 2 modules that are not going to be ported to Python 3

Python Module Fedora Python 2 package Notes
mod_python Upstream mod_python has effectively stopped since February 2007. ..."You also will never see a version of mod_python for Python 3.X as that is going to require a radical rewrite"... with various suggestions including moving to mod_wsgi
gtk pygtk2 The old C-based bindings are not going to be ported. Instead, the "Gtk" module can be accessed from pygobject introspection with upstream trying to make it easy to transition from PyGTK
