我仍然使用与之前相同的代码（我将发布更低版本），我只需要帮助将前10-15行转换为伪代码，这样我就可以自己了解如何做到这一点。
代码有效，缩进很奇怪，因为我很快就添加了空格来放入代码中。 对非专业代码道歉，我还是python的新手！ 另外，请不要做整个伪代码，直到第一次真正的循环结束，所以我可以弄明白并自己完成剩下的工作。谢谢你:)）

答案 0 :(得分：1)
在伪代码中？我试着在Python上阅读一下，真的不难理解发生了什么。基本上：
import导入此代码中所需的各种python模块
def restart_program():定义了一个函数，您可以稍后在restart_program()的代码中运行该函数
While True:表示永远做某事，或直到break。
.lower()是字符串
如果您使用此代码作为基础，它不是特别pythonic，它使用类似旧的线性基本程序的样式，过度使用While True循环。编写同一个程序肯定有更短更可读的方式。
