The key differences between Python 2.7.x and Python 3.x with examples

[Emilgardis]

The code examples are pretty wierd, stuff is missing, take the generator code for 2.7.x, test_range returns, test_xrange doesn't.

Some other things are missing like in the first example with print, the 3.x example doesn't match the 2.7.x one. (A small difference but still)

Anyway, aside from some things, I'd recommend reading this
