Prefer xrange over range for small performance gain.

range() allocates an actual list when called.  xrange() is just an iterator
and creates the next range item on demand.  This provides a slight
performance increase.

In python 3, range will do what xrange does currently, but the upgrade will
be handled by the 2to3 tool.
