TODO #7.打印游戏结果。我想重用变量score，但它声明它是未声明的，并且不确定如何不必在main函数中输入这部分。
当我运行下面的代码时，我得到以下错误：使用未声明的标识符'guess'
if（choice）

我正在努力使用它的功能之外的变量得分。choice（由程序选择的单词，基于用户选择的单词大小，由用户猜测）和guess（用户对选择的单词的猜测）。在过去的几个星期里，我看了函数的短片和讲座片段大概15遍，贯穿了多个习题集，但仍然没有完全掌握它
如何在其功能之外重用猜测和选择？这就是为什么我最终把所有东西都放在main函数中。
如果有人能给我指出这方面的学习资源，我将不胜感激。
我已经尝试了下面的代码，并尝试重新初始化所有的变量，但似乎不可行，我可能不理解的概念。
我尝试尽量减少复制的代码数量，但这并没有给社区提供所需的信息，但我不能创建一个最小的可重复的例子，也许我将能够通过更多的实践来做到这一点，但这里是完整的代码，请不要生气。
