Syntax Erro Python : Estou iniciando python pouco tempo. Não estou conseguindo resolver esse erro.

    import pygame, sys
    from pygame.locals import *
 
    pygame.init()
 
    DISPLAYSURF = pygame.display.set_mode((400, 300))
    pygame.display.set_caption('Hello World!')

    while True:
        for event in pygame.event.get():
            if event.type == QUIT:
 
            pygame.quit()
            sys.exit()
 
            pygame.display.update()
