代码如下:
import sys, pygame
from pygame.locals import *
from random import randrange
up =lambda x:(x[0]-1,x[1])
down = lambda x :(x[0]+1,x[1])
left = lambda x : (x[0],x[1]-1)
right = lambda x : (x[0],x[1]+1)
tl = lambda x :x=150:
times =0.0
s = move(s,d)
else:
times +=time_passed
for event in pygame.event.get():
if event.type == QUIT:
sys.exit()
if event.type == KEYDOWN and event.key == K_UP:
s = move(s,d)
if event.type == KEYDOWN and event.key == K_LEFT:
d=dire[tl(dire.index(d))]
if event.type == KEYDOWN and event.key == K_RIGHT:
d=dire[tr(dire.index(d))]
if s[0]==food:
s = grow(s,d)
food =randrange(0,30),randrange(0,40)
if s[0] in s[1:] or s[0][0]= 30 or s[0][1]=40:
break
screen.fill((0,0,0))
for r,c in s:
pygame.draw.rect(screen,(255,0,0),(c*20,r*20,20,20))
pygame.draw.rect(screen,(0,255,0),(food[1]*20,food[0]*20,20,20))
pygame.display.update()

说明：
1.其实不用pygame，在把一些条件判断改改，估计可以再短一半。。等以后自己python水平高了再回来试试。。
2.但是50行的贪吃蛇代码，还是有可读性的，写的太短就真没有了。。
3.关键是把旋转，移动，等等这些算法用lamda表达式实现，还有函数对象。。
4.哪位“行者”能写的更短，小弟愿意赐教....
