我一直在学习Python这个简单（对我来说）的方式：来自youtube上的sentdex的简单视频游戏示例教程。我所知道的概念在某些事物的背景下变得更加清晰，我认为这些概念就像一个简单的游戏。无论如何，我遇到了一个问题;由于某种原因，我无法获得菜单页面blit。我最初非常密切地关注本教程，着眼于标点符号，大小写和适当的缩进，因为我认为这似乎是n00bs最一致的陷阱。但是，该教程不适用于该部分，即使游戏结束，该程序也会直接进入游戏循环。我尝试了其他方法，google和youtube，但似乎没有任何工作！我得到一个非描述性的“语法错误”，但据我所知，关键位是正确的。我确定我只是一个盲目的菜鸟，但是在这段代码中会有一些简单的分析！
注意：我知道我有一些悬挂器，比如我如何导入Pickle但尚未使用它们，这些只是后续步骤的提醒，一旦这个菜单问题得到解决，很快就会充实。
运行python（使用pygame）2.7，因为我无法让pygame在python 3上运行。 我有Eric5和pycharm，我正在运行Debian Jessie带有一个backported Cinnamon（而且我相信内核，但我可能错了）
