关于python继承和参数列表的问题

Question

首先我得到了这个错误

File "E:\New folder (7)\maingame.py", line 64, in play     print self.introduction AttributeError: 'game' object has no attribute 'introduction'

我不确定这意味着什么，因为我正在从上一课中提取 self.introduction..

我也收到了

File "E:\New folder (7)\maingame.py", line 96, in <module>
game.play()
TypeError: play() takes exactly 2 arguments (1 given)

错误，但我终生无法找到它正在寻找的参数，我只是希望它能够工作。

Answer 1

“游戏”对象没有“介绍”属性

你应该在初始化游戏时调用你的超类的init。在您当前的代码中， textadventure.init 从未被调用，这就是为什么不会将介绍添加到 textadventure 的原因。

游戏也不应该从对象继承（它通过 textadventure 实现）。

class game(textadventure):
    def __init__(self):
            super(game, self).__init__()
            self.health = 100

    def play(self):
        print self.introduction

应该做的伎俩。

TypeError: play() 只需要 2 个参数（给定 1 个）

你永远不会在游戏中使用你的textadventure 参数。删除它应该可以正常工作。
