Python 巨蟒石剪刀不懂打领带

我正在做一把剪刀，一旦一方获胜，紧接着就是平局 会说前一方赢了。例如：人类获胜，平局，但表示人类获胜，并在人类得分上加一。这里发生了什么

在新一轮开始时，您尚未清除上一个获胜者

因此，在

winner

中，您发现有一个平局，并将控制权转移到

积分和\u winner\u显示

但是一旦到了那里，你首先要检查两名球员是否获胜——你最后要检查“平局”状态。
因为

self.Winner

仍然持有上一轮的值。
前一个获胜者再次被宣布为获胜者，并且

else:
    global tie

永远也达不到

只有当两名球员都没有获胜时，才会宣布平局

您可以重新安排逻辑，首先检查是否存在平局。
这将解决您眼前的问题，但会带来另一个类似的问题：
平局后，平局将被记住，此后任何球员都不能宣布为赢家

解决方案是在每轮开始时重置变量

self.Winner

。
让我们在

\uuuu init\uuuu

   def winner(self):
        global Winner

        self.Winner == None  // clear previous winner the at start of each round.

        if self.human_choice == self.computer_choice:
            self.Winner == 'tie'
            self.points_and_winner_display()
    ....

---

（如果将变量作为属性与

self.

一起保存，则无需使用

global

）在某些可能导致其不工作的位置，如果是这种情况，则使用了错误的变量。您不应该在这里使用global。谢谢。这帮了大忙，太棒了！很高兴听到这个消息。
