No, it's not none. It's an empty list; thus, python executes nothing inside the inner loop.

>>> range(2,2)
[]

>>> for y in range(2,2):
...     print 'yes, I made it to here'

See? It has no output. By the way, the python REPL is your friend! Use it often when you can't figure out what is happening.

Take care,
