[Tails-dev] Python questions

I'm new to Python programming so I don't know how much I can help, but I'd like to do what I can.  I have some questions about Python and Tails. 


What parts of Tails are written in Python?
What Python libraries are included with Tails?
Where can I find source code to the parts of Tails that are written in Python?
How hard would it be to upgrade Python on Tails to 2.7?
