Question

经过这么多个小时后，我仍然无法弄清楚如何检查我的数据中是否存在名称和密码用户输入。例如，当我问Please input customer name:并且他们输入Sam时我再次询问Please input customer password:并且输入为janos我希望调用customer_menu()函数。感谢

customers_list = []

        account_1 = Account(5000.00, account_no)
        customer_1.open_account(account_1)
        self.customers_list.append(customer_1)

           self.customer_menu()
        else:
             print("sorry %s, it doesn't look like you are a customer"%name)
             exit()


    def main_menu(self):
