私は、ユーザー アカウント オブジェクトも持つハングマン プログラムに取り組んでいます。プレーヤーは、ゲームをプレイする前に、ログイン、新しいアカウントの作成、またはアカウントの詳細の表示をすべて行うことができます。ゲームが完了すると、ユーザーの勝敗が更新されます。プログラムを終了する前に、アカウント (viewAcc 関数) を表示しようとすると、次のエラーが表示されます。
'NoneType' object has no attribute 'get_username'.
プログラムを再度実行すると、アカウントにログインできますが、アカウント情報を表示すると、勝敗が更新されていません。助けていただければ幸いです。約 8 時間以内に授業のためにこれを提出する必要があります。
クラスコードは次のとおりです。
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
そして、ここに私のプログラムのコードがあります:
