I would create tuple pairs inside of the list, like this:

mylist = [(1, "one"), (2, "two"), (3, "three")]

for (number, word) in mylist:
   print number, word

Since the tuples are immutable you don't have to worry as much that
the pairs could get screwed up and its very simple to iterate over.
There might be a performance hit for a long list, but for most things
would probably be fine.
