This session will consist of two parts. In the first one, I'll talk about Python 3 in general and why Fedora will benefit from switching to it, then I'll discuss the system wide Change "Python 3 as Default" proposed for Fedora 22 (https://fedoraproject.org/wiki/Changes/Python_3_as_Default) and its current state. The second part will be dedicated to a discussion and Q&A about porting from Python 2 to Python 3 and impact of the system wide Change. This presentation isn't targeted only at Fedora Python packagers and developers. It also aims at people who don't know much about Python, but want to find out where Fedora is going with this language.
