Andrew Kuchling (@akuchling) speaks on porting to Python 3.
I'll take three small-to-medium libraries or applications from the Python Package Index and discuss the process of porting them to Python 3.3. Topics will include a short overview of the differences between Python 2 and 3, converting code with the 2to3 tool, and the issues presented by string/Unicode processing.
Intermediate. Aimed at developers who haven't tried porting anything to Python 3.x yet.
