In python is there an easier way to write 6 nested for loops?

Question

This problem has been getting at me for a while now. Is there an easier way to write nested for loops in python? For example if my code went something like this

Answer 1

Technically, you could use itertools.product to get a cartesian product of N sequences, and iterate over that:

 for y, x, y1, x1 in itertools.product(range(3), repeat=4):
   do_something_else()

But I don't think that actually wins you anything readability-wise.
