我不能在pygame中制作黑屏

Question

我正在使用python 2.7 32位窗口和pygame 1.9.1

import pygame, sys
from pygame.locals import *

pygame.init()
DISPLAYSURF = pygame.display.set_mode((400, 300))
pygame.display.set_caption('Hello World!')
while True: # main game loop
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
    pygame.display.update()

错误信息是：

Traceback (most recent call last):
  File "C:/Python27 32bit/Scripts/test.py", line 1, in <module>
    import pygame
  File "C:/Python27 32bit/Scripts\pygame.py", line 2, in <module>
ImportError: No module named locals
