My advice would be to go read up on the zip() function and the
str.join() function. Then, if you are using python 2.x, go find
itertools.izip. It does the same thing as zip but it's more memory
efficient. With those two you can do it in about two lines or so (and
maybe a few for set up and clarity and such).

If you get stuck, don't hesitate to ask.
