Hi,
http://www.linux-magazine.com/Online/News/Fedora-13-beta-goes-live
"With Goddard comes a number of updates and new features for end users and developers alike. For the first time in Fedora history it's possible to install a Python 3 stack in parallel to the current Python 2.6, allowing developers to better optimize and increase the compatibility of their work. Another treat for developers is an improved GNU debugger that allows unified information for C/C++ libraries and Python, all in the same running process"
