我在逛Quora的时候发现这么一个问题：
What is the most beautiful program you ever coded in Python?
有网友分享了自己用turtle或者pylab画出来的酷炫图形。
前两个是用turtle画的动态图（简书可以传动图吗？），第三个是用pylab画的静态图，原来用pylab也能画出这么多彩的图形。
<code>
from turtle import*
from time import sleep
title("fanatic")
bgcolor("white")
speed(0)
ht()
pu()
goto(-400,0)
pd()
tracer(False)
L=["green","yellow"]
for i in range(5,101,2):
for j in range(i):
for z in range(40):
pencolor(L[z%2])
fd(20)
rt(180-180/i)
tracer(True)
sleep(0.03)
tracer(False)
clear()
'''
'''
from turtle import *
from random import randint
speed(0)
bgcolor('white')
x = 1
while x < 400:
r = randint(0,255) #让颜色随机变化
g = randint(0,255)
b = randint(0,255)
colormode(255)
pencolor(r,g,b) # 根据r,g,b的值改变笔触颜色
fd(50 + x)
rt(90.911)
x = x+1
