我一直在尝试创建一个石头剪刀布游戏[Sort of;-)]，但由于某种原因，当计算机获胜时它不显示它，它给了我一个错误。谁能把代码读一遍，告诉我是什么问题。(我对编码很陌生，可能有一百万错误，所以请解释清楚)

我不认为StackOverflow得到我的缩进正确。如果你想要原始文件，在这里。https://drive.google.com/open?id=0BxbNlq7y4nLxMHp2WVF5OUNqd3M
您获得的KeyError表示您正在尝试访问字典中不存在的键。查看您的代码，似乎您的self.messages字典没有在所有子字典中包含'Paper'作为键。
现在，让我们看看并尝试改进这段代码。首先，print调用不需要这么混乱。
def show_hand(self):
print(("You played ", self.hand[self.human], " the computer played ", self.hand[self.computer], "!"))
可以
def show_hand(self, human, computer):
print("You played {}, the computer played {}!".format(human, computer))
现在，只需将变量传递给方法调用。
进一步，让我们来处理beats方法。我们可以使用相同的过程，传入self。人类和自我，电脑。这样可以在代码中省去很多额外的噪音:
def beats(self, human, computer):
if human == computer:
return "It's a tie!"
现在，让我们处理用户输入处理。这可能会容易得多!您可以合理地期望字符串(表明用户输入了paper之类的东西)或整数。所以为什么不在将输入传递到游戏中时验证它呢?
def __init__(self, human):
...
if human.isdigit():
self.human = int(human)
else:
reversed = {v.lower(): k for k, v in self.hand.iteritems()}
self.human = reversed.get(human.lower())
if not self.human:
raise Exception("Not a valid choice")
繁荣,做。
我发现了什么是错误的，它想让我写这样的if语句
`if self.hand[self.computer] == "Rock" or self.hand[self.computer] == "Scissors" or self.hand[self.computer] == "Spider-Man" or self.hand[self.computer] == "Wizard":
return self.message[self.hand[self.human]][self.hand[self.computer]] + " You Win!"
else:
return self.message[self.hand[self.computer]][self.hand[self.human]] + " The Computer Wins!"`
我认为把or放在两个条件之间就足够了。
