The Python tutorial is a good place to start:

    https://docs.python.org/3.4/tutorial/index.html

For your particular problem you'll probably want to use the
itertools.product function:

    https://docs.python.org/3.4/library/itertools.html#itertools.product

I wouldn't recommend printing out every possible combination to the
screen, though. That's over a million rows! Start with fewer pairs (4
is probably good), or write them to a file instead.
