We use Python a lot within Fedora; key system components such as anaconda and yum are written in Python - Python 2, that is. We added a Python 3 stack in Fedora 13, parallel-installable with the main Python 2 stack [1] Since then, we've been slowly building out the Python 3 stack. You can see the current status here: http://fedoraproject.org/wiki/Python3 So Python 3 is usable on Fedora - I've used it myself on some new code that I've written, and the new version of the language does "feel nicer" than Python 2 to me. If you're want to help get more Python 3 into Fedora, there are at least two ways I can think of: - help upstream projects port from Python 2 to Python 3. This may mean e.g. adding new automated test coverage to the existing project, since having good automated test coverage is invaluable. - help package Python 3 code for Fedora. But it's important to work with upstream on this: don't just run 2to3 on the code. I hope that at some point enough of the underlying stack will have been ported to Python 3 that yum and anaconda can switch over (they need to do so together) - but that's a judgement call for the yum and anaconda folks to make. Last time I looked, anaconda had a _lot_ of dependencies, many of them very old code, without great automated test coverage. So writing automated tests for those deps might be a place to look at, for those interested in this. Some other distributions have changed /usr/bin/python to signify python 3, rather than python 2. I don't see us doing that at this time: it would break too many things, and I don't see any real benefit. > And gnome3 to python3...? That's already possible, to some extent; the gobject-introspection code supports both Python 2 and Python 3. So if you have a .gir interface file for a library, in theory you already have Python 3 bindings for that code (This is in Fedora 15 onwards as the python3-gobject rpm, built as as a subpackage of pygobject2; I did some of the early work on the Python 3 port, but John Palmieri and others know far about this than I).
