Question

class game_type(object):
    def __init__(self):
        select_game = raw_input("Do you want to start the game? ")
        if select_game.lower() == "yes":
            player1_title = raw_input("What is Player 1's title? ").lower().title()


class dice_roll(object,game_type):
    current_turn = 1
    current_player = [player1_title,player2_title]
    def __init__(self):
        while game_won == False and p1_playing == True and p2_playing == True: 
            if raw_input("Type 'Roll' to start your turn  %s" %current_player[current_turn]).lower() == "roll":

我一直收到一条错误，内容如下： NameError：名称'player1_title'未定义

我理解标题是一个函数，所以我尝试使用player1_name和player1_unam，但这些也返回了相同的错误：（

有人可以帮忙吗

非常感谢所有答案

导致NameError的内容很多。

首先，game_type的__init__方法不保存任何数据。要分配实例变量，您必须使用self.指定类实例。如果不这样做，那么您只需分配局部变量。

其次，如果要在子类中创建一个新的函数并且仍然需要父类的效果，则必须使用__init__显式调用父类的super()函数。

基本上，你的代码应该是

# Class names should be CapCamelCase
class Game(object):                                                                
    def __init__(self):                                                    
        select_game = raw_input("Do you want to start the game? ")         
        if select_game.lower() == "yes":                               
            self.player1_title = raw_input("What is Player 1's title? ").lower().title()
            # Maybe you wanted this in DiceRoll?
            self.player2_title = raw_input("What is Player 1's title? ").lower().title()

# If Game were a subclass of something, there would be no need to 
# Declare DiceRoll a subclass of it as well
class DiceRoll(Game):                                                      
    def __init__(self):                                                   
        super(DiceRoll, self).__init__(self)                               
        game_won = False                                                   
        p1_playing = p2_playing = True                                     
        current_turn = 1                                                   
        current_players = [self.player1_title, self.player2_title]    
        while game_won == False and p1_playing == True and p2_playing == True:
            if raw_input("Type 'Roll' to start your turn %s" % current_players[current_turn]).lower() == "roll":
                pass

当我尝试运行这段代码时，我不断收到命名错误（Python）
