Python 如何在游戏结束后重放游戏，而不关闭程序并在PYGAME中再次运行它？
我用python制作了一个乒乓球游戏：Pygame。它运行得很好，我决定修补它的一些漏洞。在游戏结束时，当屏幕上显示游戏时，我必须关闭游戏，然后返回主源代码并再次运行它。因此，我决定添加一条消息“按一个键播放”，并且我还添加了一个检查按键的功能。信息会显示，但一旦按下一个键，它就无法检测到。 这是Python 如何在游戏结束后重放游戏，而不关闭程序并在PYGAME中再次运行它？,python,pygame,Python,Pygame,我用python制作了一个乒乓球游戏：Pygame。它运行得很好，我决定修补它的一些漏洞。在游戏结束时，当屏幕上显示游戏时，我必须关闭游戏，然后返回主源代码并再次运行它。因此，我决定添加一条消息“按一个键播放”，并且我还添加了一个检查按键的功能。信息会显示，但一旦按下一个键，它就无法检测到。 这是checkForKeyPress（）：code: def checkForKeyPress(): keys = pygame.key.get_pressed() if not any(k
