这是一个非常奇怪的错误，我不知道发生了什么。基本上我的代码是最重要的，它还没有完全完成，但无论如何。对于那些玩过顶级王牌的人，我的代码模拟了两只手之间的牌传递。但是，如果您查看if len(Your_Hand)== 0:我使用 len() 打印这些手的长度的第 129 行 ()，它们不会相加。即 len() 表示读取列表时显然不正确的长度？

谢谢，如果您能看一下并尝试帮助我了解正在发生的事情，那将是很棒的！

这是我的代码：

几轮之后，我的手牌长度为 3，由一张罗恩韦斯莱牌和两张空单组成：[('Ron Weasley', 12, 13, 4, 5), [], []]。我猜你不想在那里有那些空列表。

罪魁祸首似乎是这一行：

Your_Hand.append(clash_pile)

这总是会在您的手上添加一个空列表。

你可能想要extend而不是append. 此外，您应该在将冲突堆重置为之前将冲突堆添加到获胜者的手上[]。

其他观察结果可能与您的原始问题无关：

  • if可能if Your_Hand[0][catagory_exchange[choice]] == Opponent_Hand[0][catagory_exchange[choice]]:应该是elif
  • 无论谁实际上赢得了冲突，您都会在冲突堆中获得牌
  • 当我拿走对手的最后一张牌时，游戏并没有结束
  • 如果每张牌都进入冲突，玩家就没有什么可打的了（尽管这可能是顶级王牌固有的问题）

我重写了你的程序，它现在对我有用。我发现了几件事：

最大的问题是@Kevin 在他的回答中指出的问题：您使用list.append()而不是list.extend()从clash_pile.

此外，category_exchange包含偏离 1 的值。每张卡片中的第 0 项是一个字符串，选择brains会导致卡片名称之间的字符串比较。（当我不断地和 Neville Longbottom 赢牌时，我很困惑！）

我重写了移动卡片的代码。我不是先调用.append()然后调用.remove()，而是调用.pop()删除值并返回它，然后在内部进行.append()。当这一切都在一行时，您不太可能看到有人只更改两行代码之一的错误。

此外，我不是在找到可接受的输入时标记变量来发出信号，而是使用无限循环并在找到可接受的输入时简单地中断。

此外，我没有使用标志变量来表示“冲突堆中有卡片”之类的东西，或者检查卡片列表上的长度为 0，而是将其更改为直接检查列表值。

另外，由于我很懒，我让程序接受一个类别的数字。而不是打字knowledge，你可以只打字2，它就可以工作。

如果您有任何问题，请告诉我。
