From Fedora Project Wiki
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.

Python modules that appear to not yet be ready for Python 3 packaging
Please let us know if this information is out-of-date.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 | |
| 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 | |
| krbV | python-krbV | Implemented in C, would need porting (with 2to3c ?) | |
| ldap | python-ldap | Porting discussed on upstream mailing list on 2009-09-03 but appears not to be done yet | |
| libvirt | libvirt-python | Porting has not yet started | |
| libxml2 | libxml2-python | Porting doesn't seem to have started | |
| MySQLdb | MySQL-python | As of 2011-07-25, http://pypi.python.org/pypi/MySQL-python/ said " Python-3.0 will be supported in a future release." | |
| nss | python-nss | Looks like we need to port it, and would be non-trivial | |
| parted | pyparted | Looks like we need to port it | |
| PIL | python-imaging | As of 2010-01-28, upstream website says "The current free version is PIL 1.1.7. This release supports Python 1.5.2 and newer, including 2.5 and 2.6. A version of 1.1.7 for 3.X will be released later." A 2010-02-21 mailing list post suggests that the port is stalled | |
| pylons | python-pylons | As of 2010-04-09, it's on the future roadmap for 1.1; see also http://pylonshq.com/project/pylonshq/ticket/425 | |
| sphinx | python-sphinx | Upstream added Python 3.x support to trunk on 2010-07-28 | |
| wx | wxPython | As of 2010-02-03, appears not to be ported yet; see http://stackoverflow.com/questions/720806/wxpython-for-python-3-0 | |
| xdg | pyxdg | Appears to not yet be ported; see RHBZ #555620 |
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 | |
| BeautifulSoup | python-BeautifulSoup | 3.1.0 adds Python 3 support, but reportedly doesn't work as well as 3.0.8 (See http://www.crummy.com/software/BeautifulSoup/3.1-problems.html http://groups.google.com/group/beautifulsoup/browse_thread/thread/f24882cc17a0625e and http://stackoverflow.com/questions/149585/beautifulsoups-python-3-compatibility ). However, beautifulsoup4 (see above) adds Python 3 support |
| dbus | dbus-python | |
| 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 |
