Python 小问题

import pygame,sys import time import random

pygame.init() screencaption=pygame.display.set_caption('打砖块') screen=pygame.display.set_mode([640,480]) screen.fill([255,255,255]) blockx = 20 blocky = 20 blockxgap = 80 blockygap = 32 while blockx <= 640: while blocky <=460: pygame.draw.rect(screen,[255,0,0],[blockx,blocky,40,20],0) blocky = blockx+blockygap blockx = blockx+blockxgap

pygame.display.flip() while True: for event in pygame.event.get(): if event.type==pygame.QUIT: sys.exit() 这段代码的循环死循环了 要怎么解决？
