您必须知道，当函数到达return语句时，它就结束了。例如，如果在return语句之后打印某个内容，它将永远不会被打印

好吧。这有很多问题脚本。首先，我觉得自己是第一个strchecker（）函数。没有正当的理由存在，因为它只被正确地使用过一次。第二，您不需要仅仅为了使循环无限地进行而分配一个变量，直到满足一个条件（这是您的脚本中最缺少的）。你知道吗

介绍：While True语法：

while True:
    do stuff
    if stuff == stuff i wanted:
        break
    else:
        pass

这里的else-pass意味着只要转到循环的顶部并继续，这通常是隐含的，您不需要在while-True循环中显式地编写else-pass部分。你知道吗

这里是你的脚本的一个修改版本，它使用了这个概念，我已经替换了大多数我认为效率低下的东西，并且改变了代码的动态性，但是我相信本质仍然存在。你知道吗

注：variablec是一个计数器，variableinp代表输入并存储最终的yes/no输入，分数是计算出来的，只是简单地打印出来，而不是str操作和格式化（我相信你可以自己做），为了更容易遵循PEP8标准（例如：将问题列表拆分为问题列表和选项列表），我们进行了一些更改。你知道吗
