主代码

1. 我真的不知道为什么我总是出现元组错误代码看起来不错
2. 现在这只是我游戏的循环部分，就是这样

        import pygame 
    
    
    # important window variables
    WIDTH, HEIGHT = 900, 500
    
    WIN = WIDTH, HEIGHT
    
    SCREEN = pygame.display.set_mode((WIN))
    
    pygame.display.set_caption('SPACE GAME')
    
    WHITE = (0,0,0)
    
    # display function (what shows up on the screen)
    def display():
        WIN.fill(WHITE)
        pygame.display.update()
    
    
    # main function/loop function
    def main():
        run = True
        while run:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    run = False
    
            display()
        pygame.quit()
    
    
    if __name__ == '__main__':
        main()
