There's also itertools.zip (and a bunch of friends) which handles long
lists like the two_iter_generator function Mark gave, building only as
necessary instead of up front. This is also very useful for zipping
lists where one or more of the sequences being zipped isn't a list at
all but an iterator, for example reading a large file.
