Rock Paper Scissors Competition

Question

In my Comp Sci course we had a Rock Paper Scissors competition between different python programs. Only rule is you can’t use a random generator,
How would you approach this competition?

Answer 1

I would (finally) research how the typical pseudo-random-generator works and try to write my own. ;-)

(Wait - is that cheating?)

Answer 2

import time and use it as a random choice like:
choice = time.time()%3
