所以我们的想法是，游戏将打开菜单，用户可以在其中选择一个级别，简单、中等、困难，或者退出游戏。现在所有发生的事情是游戏打开时出现黑屏，大小与我的游戏大小 (1024, 768) 一样，关闭、最大化和最小化都不可点击。非常感谢任何帮助。

最佳答案
在您的程序中，您绝不会启动 main() 函数或与此相关的任何其他内容。
许多 python 脚本底部的常见部分是:
if __name__ == '__main__':
main()
如果脚本是顶级 python 文件，这用于启动所有内容
将其包含在底部，这将帮助您入门。
完成此操作后，您会发现在函数中调用的许多变量都是本地变量(我猜整个问题是基于您编写程序然后尝试将所有内容绑定(bind)到函数中这一事实) 所以你需要将它们声明为全局变量，但这超出了这个问题的范围。
希望这对您有所帮助。
