用pygame学游戏开发的问题，直接上代码，菜鸟级问题，大神莫喷。

#我的问题是，执行以下代码后，按f切换到全屏，然后屏幕它会一闪一闪的，奇葩到不得了。
background_image_filename = "E:\\pygame_program\\screen_mode\\woailuo.jpg"

import pygame
from pygame.locals import *
from sys import exit

pygame.init()
screen = pygame.display.set_mode((640,480),0,32)
background = pygame.image.load(background_image_filename).convert()
Fullscreen = False

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            exit()
        if event.type == KEYDOWN:
            if event.key == K_f:
                Fullscreen = not Fullscreen
        if Fullscreen:
            screen = pygame.display.set_mode((640,480), FULLSCREEN,32)
        else:
            screen = pygame.display.set_mode((640,480),0,32)
        screen.blit(background,(0,0))
        pygame.display.flip()
