Answer 1

问题是这一行：

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert

有了这个任务，你的background就是一个函数。你需要这样称呼它：

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert()

Answer 2

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert的convert部分是函数还是方法？如果是这样，你就错过了后面的()。

将该行更改为

GAME_SPRITE['background'] = pygame.image.load(BACKGROUND).convert()

，看看它是否达到了您的预期。

如果这解决了您的问题，那么问题是您已将convert函数分配给GAME_SPRITE['background']，而不是调用convert()并分配返回值。
