原标题：使用Python的turtle画炫酷图形

例子一：

import turtle

t = turtle.Pen()

turtle.bgcolor("black")

sides=6

colors=["red","yellow","green","blue","orange","purple"]

for x in xrang(360):

t.pencolor(colors[x%sides])

t.forward(x*3/sides+x)

t.left(360/sides+1)

t.width(x*sides/200)

print("####结束####")

效果图如下：

例子二：

可以做成交互的，利用eval函数获得用户想绘制的边数

代码：

import turtle

t = turtle.Pen()

turtle.bgcolor("black")

sides=evali(input("输入要绘制的边的数目，请输入2-6的数字！"))

colors=["red","yellow","green","blue","orang
