关于python：如何为我的多选故事的if语句添加while循环？

How do I add a while loop to an if statement for my multiple choice story?

我正在尝试在我的if语句中添加一个while循环，该循环附加到另一个while循环。我不确定我哪里出错了。我正在尝试自己学习Python，所以我不太了解。

我收到一条错误消息，说"线路延续字符后面的意外字符。它突出显示我在第一个引号后面的最后一个'if'语句。如果我要把它拿出来，它会突出显示最后一个True语句。

你看到的＃是来自另一篇文章。

基本上，我的问题是如何为我的故事修复下一个while循环语句？对于我未来的多种选择，这个过程是否相同？

在python中，获得正确的缩进和变量的范围非常重要。

第一个"休息"错误缩进。还需要一个标签。
双引号外的d2a选项中的 n。
d2a响应的if语句拼写错误。再将它们移出一个标签。

我在这里整理了一些代码。
注意：我在要打印的每行文本周围加上双引号。更容易看一下。

第17行的新行字符( n)需要包含在字符串中(即它需要在引号内) - 这就是导致该特定错误消息的原因。

另外，第6行的break语句需要缩进。除此之外它应该工作 - 请注意，您需要在终端中输入'a'作为输入才能使其工作 - 您可以使用raw_input代替然后您只需键入a
