I've been having some problems with using a while statement for one menu
within another while statement for the main menu, first time I've done
it. It's with choice number two from the menu. When I run the program,
I get a UnboundLocalError: local variable 'ai' referenced before
assignment. I initialize ai as "", but then it just skips to the you
choose scissors I choose and nothing shows up. As soon as I take away
the while again[0] == "y": statement, the program is fine again which
leads me to think I'm just placing it in the wrong place. I just want
to ask the user if they would like to play again and loop them back to
the weapons menu if they choose yes. If they choose no, loop them back
to the main menu. I've placed the question again=raw_input("Would you
like to play again? ") at the end the tasks for menu choice two. Ignore
three....one step at a time. ;)
thx
