您必须知道，当一个函数到达return语句时，它将结束。因此，例如，如果您在return语句之后打印某些内容，则永远不会打印

好的。这个脚本有很多问题。首先，我感觉像第一个strchecker（）函数。没有合理的理由存在，因为仅正确使用了一次。其次，您不需要分配变量就可以使循环无限循环直到满足条件（这是脚本中最缺乏的）。
简介：While True语法：
while True:
do stuff
if stuff == stuff i wanted:
break
else:
pass
现在这里的其他传递意味着只需要循环到顶部并继续，这通常是隐含的，您不需要在True循环中显式地编写其他传递部分。
这是使用此概念的脚本的修改版本，我替换了我认为效率低下的大多数内容并更改了代码的动态，但我相信本质仍然存在。
注意：变量 c 是一个计数器，变量 inp 代表输入并存储最终的是/否输入，仅计算分数但只打印输出而不是str操作和格式设置（我敢肯定您可以自己做），为了使遵循PEP8标准更容易（例如：将questionsList分为questionsList和option_list），存在一些更改。
