slightly less obscure:

    for i in range(len(list1)):
        item1 = list1[i]
        item2 = list2[i]
        ...

the slightly more obscure way:

    for item1, item2 in map(None, list1, list2):
        ...

note that future Python versions may also support
something like:

    for item1 in list1; item2 in list2:
        ...

but that's another story.
