that was interesting, and I've searched for info. there is a function for this in Python's standard module 'itertools'. look at my code: http://www.sololearn.com/app/sololearn/playground/ctmEhmAQOsfI/ in future, try finding some info by yourself first, it's a really great skill for a good programmer.
