class - Python: 'NoneType' object has no attribute 'get_username' -
i'm working on hangman program has user accounts objects. player can log in, create new account, or view account details, of work fine before playing game. after game has completed, user's wins , losses updated. before exiting program, if try view account (the viewacc function) error:
'nonetype' object has no attribute 'get_username'. when run the program again, can log in account, when view account info wins , losses haven't been updated. appreciated, have turn in class in 8 hours.
heres class code:
class account: def __init__(self, username, password, name, email, win, loss): self.__username = username self.__password = password self.__name = name self.__email = email self.__win = int(win) self.__loss = int(loss) def set_username (self, username): self.__username = username def set_password (self, password): self.__password = password def set_name (self, name): self.__name = name def set_email (self, email): self.__email = email def set_win (self, win): self.__win = win def set_loss (self, loss): self.__loss = loss def get_username (self): return self.__username def get_password (self): return self.__password def get_name (self): return self.__name def get_email (self): return self.__email def get_win (self): return self.__win def get_loss (self): return self.__loss and here's program's code:

your play() function doesn't have return statement, means it's returning none return value. that's how you're getting none user variable in main(). add return statement play() function , should fine.
