Question

首先，为这个沉重，直截了当的代码感到抱歉。我知道那里有一些更好，更吸引人的代码，但我决定自己编写。我知道还有很大的进步空间，但请耐心等待。

除分数部分外，几乎所有我的代码都能正常工作。

基本上这是一个剪刀石头布游戏，其中记录了玩家，计算机和游戏总数的获胜次数。

我只能将分数传递给另一个函数。有人可以让我知道为什么我在重复游戏功能中选择“ 1-得分”时会收到此错误

Answer 1

您想配对

    return player, computer, total, repeat_game()

打这样的电话：

    player, computer, total, repeat_game = play_game()

也就是说，如果公共API返回了四个值，那么您将希望获取这些值。

四个数字开始变得不方便。您最好定义一个class并存储四个对象属性，例如self.player。
