There are two answers: first, if your domain interest is spell-
checking, search for "phonetic algorithm" or "soundex python". If your
interest is iteration, check out itertools - AFAIK this is the closest
you will get to a simple syntax for iterating over the diagonal as
opposed to the Cartesian product.
>>> from itertools import *
>>> for x,y in izip('painter','paintor'):
... print x == y
