Python 如何修复老虎机错误

我不得不为一个班级项目设计一个吃角子老虎机，由于某种原因，这个程序一直在崩溃。我不确定我输入的代码是否有问题，或者我是否遗漏了什么。我们被告知只使用红皮书第3、5、9章中inventwithpython手册中的信息。非常感谢您对本代码的任何帮助

我不确定这是否是有意的，但看起来IMAGELIST1和2中的文件名以大写字母“Santa.png”开头，而IMAGELIST3中的文件名以小写字母“Santa.png”开头

当您的程序进入ReturnWinning函数时，似乎没有任何小写字母。那可能是你的问题。试试看它是否有效。

定义崩溃。这会使你的电脑崩溃吗？它是否抛出python错误？什么错误？由于程序正在崩溃，您应该调查诊断和调试设施，以找出程序中发生崩溃的位置。当你知道崩溃发生在哪一行时，你应该能够找出它崩溃的原因。你能给出失败的Highlight代码吗？游戏崩溃的原因是什么？python代码本身不会导致错误，而是在它启动pygame时，pygame程序冻结，在我尝试按下旋转按钮的那一刻没有响应。我认为错误来自于我用**粗体显示的部分。这是整个代码还是有其他部分？因为你有星号的部分在程序中没有被调用，所以我不知道这是否真的是问题所在。
