我不知道发生了什么

Question

我正在尝试用python3.4.3编写pygame1.9.2，它给了我一个我完全不理解的错误。代码是一个基本的hello world：

import sys
import pygame
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()

下面是我得到的错误：
