Update to Python 3 Cheat Sheet for students

[Laurent Pointal]

Hello and happy year 2013,

I just updated my Python 3 Cheat Sheet for students leaning programming, to 
version 1.2.1 (fix with open() as f syntax, add enumerate() in loops).

Its available here, in english and in french:

A+
Laurent.

PS. The (longer) Python 3.2 reference card is here:
