如何在python3中修复我的hangman游戏中的错误

Question

这个代码来自一个小游戏，我在过去的一天左右，我知道我不应该真正张贴整个代码，但我不完全确定代码的哪一部分没有按预期工作，任何帮助将不胜感激。代码是一个刽子手游戏，我知道在代码中有大量的重复，但不确定如何将它减少到每一个功能，将工作在每一个困难设置。在

我不知道单词出了什么问题，也不知道如何解决它。在

您的words变量只在build_word_list函数的作用域中定义。 所有其他函数都不能识别它，所以你不能在那里使用它。在

您可以通过defining it as a global variable获得“快速修复”，尽管通常是using global variables isn't the best practice，而且您可能需要考虑其他解决方案，例如将words传递给使用它或在类范围内使用它的其他函数。在

（如果您对避免全局变量感兴趣，您可能想阅读this和this）
