This is a homework thing. I am in the online section of an intro Python course. We are supposed to create a program for our final that allows the user to select if they are a new or returning player. If they are a new player, a new .rps file should be created through pickle that stores the users win/loss/tie statistics. If the player is returning, they should be able to load their "name".rps file so that all of their statistics are loaded into the proper places.

I am having a horrible time using pickle. I have put probably 30 hours into this (hard to believe looking at the horrible code). I really need help with finding a way to use pickle to create and access the files generated by the program. I think I can fix any other problems with the program. It has just made me feel incredibly dumb. The TA's for the course haven't responded to emails and the professor replied with an "email the TA's" answer. I'm lost and alone.

    displayScoreBoard()

# creates the welcomemenu function which displays start screen and requests user input. Opens .rps file for returning players.
