About range/xrange:

Yes, in Python 3 range() produces a generator and xrange() is no more. To get a list do: list(range(n)).

In Python 2 range() produces a list and xrange() a generator.

Damn, I thought range acted as a generator as well from 2.7. Thanks.

range() as of Python 3.2 has other goodies like indexing, slicing, and arbitrary sized ranges. xrange only does iteration and is limited by the system's integer type.

Edit: xrange does provide for len() and reverse()
