python3.3pygame1.9.2a0（64位）图形窗口显示第一个图像，但随后冻结

Question

我在教室电脑上使用Python2.7.3和Pygame，创建了一个电影报价猜谜游戏，使用命令提示窗口（与用户交互）和图形窗口（显示静态.png文件，如电影中的照片）。比赛进行得很成功。在

现在我想在我自己的Windows7 64位PC上运行和增强游戏。我下载了Python版本3.3.5和pygame-1.9.2a0.win-amd64-py3.3.exe。然后我对我的游戏代码做了两个修改，从Python2.7.3调整到Python3.3.5环境：（1）从“raw_input（）”命令中删除了“raw_200;”；以及（2）删除了第1行，指导老师告诉我们使用该行，以便Python2.6的操作与以后的版本一样：“fromfuture导入除法，绝对导入，打印函数，unicode_文字”。在

现在，在我的电脑上，命令提示符窗口和音频都能正常工作。pygame图形窗口只显示first.png图像。窗口顶部（在pygame徽标旁边）立即显示“（无响应）”。没有错误消息。谢谢你的帮助。在

PyGame是一个事件驱动的系统。如果你不使用它的内部事件循环来驱动你的游戏，你仍然需要让它偶尔花一些时间来处理内部事件，比如移动或调整窗口的大小。有一个专门用于此的函数：^{}。在

我认为，如果在代码中的几个位置（也许就在控制台上收集输入之前或之后）对该函数的调用，您可以使屏幕响应。在
