Telling us this without the stack trace is pretty unhelpful. The Python exceptions include a very good stack trace (with line numbers +- 1 line) and a decent description. This error means that wherever this error was raised was a reference to the name "bet" and it had no reference to any "bet" at that point. The reasons could be that you forgot to assign a value to the name first, maybe it was a typo, in a preceding function, forgot the reference to self, etc, etc. I took a *quick* look at the code and found this (I did not check for other problems or if this error happens in more than one place): class BJ_Player(BJ_Hand, Bet): """ A Blackjack Player. """ def is_hitting(self): response = games.ask_yes_no("\n" + self.name + ", do you want a hit? (Y/N): ") return response == "y" def bust(self): print(self.name, "busts.") self.lose() def lose(self): print(self.name, "loses.") betting = Bet() bet.stash -= bet.wager def win(self): print(self.name, "wins.") bet = Bet() bet.stash += bet.wager def push(self): print(self.name, "pushes.") There are a couple things wrong with this class. First, you never define an __init__ which might be technically okay but is unlikely to be what you want for any user defined class (especially one with multiple inheritance). Since there is no __init__ defined, it will call the first parent class BJ_Hand.__init__ but not the second parent class Bet.__init__ (if it has one). Next for BJ_Player.lose(), bet is never defined and thus neither is bet.stash. Maybe you meant betting.stash -= betting.wager? I bet if you ran lint/pylint on this module it would have told you the error without even having to run it.

If a player loses they will be removed from the game. I keep getting the error: “NameError: global name 'bet' is not defined.” I know I came across this error before in a previous thread, but I am confused on how to solve this, since I am also trying to juggle it with inherited methods at the same time.
