Python 3.3 pygame 1.9.2a0（64位）圖形窗口顯示第一個圖像，但然後凍結

Question

在教室PC上使用Python 2.7.3和Pygame，我創建了一個電影引用猜測遊戲，使用命令提示符窗口與用戶交互）和圖形窗口（以顯示靜態.png文件，例如來自電影的照片）。遊戲成功運行。

現在我想在我自己的Windows 7 64位PC上運行和增強遊戲。我下載了Python版本3.3.5和pygame-1.9.2a0.win-amd64-py3.3.exe。然後，我對遊戲代碼做了兩處更改，以便從Python 2.7.3調整到Python 3.3.5環境：（1）從「raw_input（）」命令中刪除「raw_」;和（2）刪除第一行，該教師告訴我們要使用，以便Python 2.6能夠像更高版本一樣操作：「從將來導入分區，absolute_import，print_function，unicode_literals」。

現在，在我的電腦上，命令提示符窗口和音頻都正常工作。 pygame圖形窗口只顯示第一個.png圖像。窗口頂部（pygame標誌旁邊）立即表示「（不響應）」。沒有錯誤消息。感謝您的任何幫助。

pygame的是一個事件驅動的系統。如果你不使用內部事件循環來驅動你的遊戲，你仍然需要偶爾花些時間來處理內部事件，比如窗口被移動或調整大小。有一個特別的功能：pygame.event.pump。

我想你可以讓你的屏幕響應，如果你在幾個地方（也許只是在控制檯上收集輸入之前或之後）在你的代碼中調用該函數。
