I recently started learning python in school as my first language and received a homework task asking us to create a simple rock paper scissors game but with a twist (mine's an RPG) and I thought it would be good if I made it so you would have to answer withing a time limit. I checked a few other threads, but I wasn't sure how to implement that code into my program, so I decided to ask here. I'm very new to python so any simple answers would be preferred if possible.
Thank you advance!
EDIT: tomh1012 gave some advice and I took it but my timer still does not work. There isnt any error on anything, it simply does not work! Any help is greatly appreciated. Also, for whatever reason, my teacher hasn't taught us functions yet so I don't really understand them much.
