strange_man()

我的问题出在奇怪的曼函数中，当我选择“正确”时，它会回到 good_door 函数而不是应该的 evil_door 函数......我不知道它为什么这样做！我似乎是对的：/

next == "left" or "Left"

应该

next == "left" or next == "Left"

或者

next in ["left", "Left"]

"Left" 总是解析为 True 并且X or True永远为真。这同样适用于你所有的析取。

为了回答您的评论，我个人会这样实现：（这并不意味着您的解决方案不如我的可行，我只是尝试给出一些想法）

class Location:
    def __init__ (self, welcome, menu, choices):

        while True:

            room = World.locations [room]

World.enter ()

嗯，语法高亮似乎弄乱了多行字符串文字。

我通过名称而不是简单地通过引用来引用位置的原因是为了允许图表中的循环。
