What is the assignment and what is your question?  You should not expect that it will be solved for you.  It is against the rules here, and it would also be unfair to yourself as you would miss the chance to learn.  On the other hand, you can get advices here.

Think of the left / right as something like a coin toss.
With a coin, you either get heads, or tails (ignoring the possibility of landing on the edge, of course).

So, I interpret these as two possible directions that can be taken at each decision point.

This documentation page talks about generating "random" numbers with Python:
