根据我的注释写出python程序：导入pygame初始化pygame定义窗口screen大小为600400定义窗口名为game点击叉叉退出游戏

import pygame

pygame.init()

screen = pygame.display.set_mode((600, 400)) pygame.display.set_caption("game")

running = True while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False

pygame.quit()
