本文介绍了一个使用Python的Turtle模块绘制复杂螺旋图案的例子。通过改变画笔颜色和方向，绘制了一系列交错的圆形弧线，形成了独特的视觉效果。

import turtle
turtle.setup(850,450,200,200)
turtle.speed(3)
turtle.penup()
turtle.fd(-250)
turtle.pendown()
turtle.pensize(20)
turtle.shape('turtle')
turtle.shapesize(2)
turtle.color('green')
turtle.seth(-90)
j = 0
colors=["red","orange","yellow","green","blue","indigo","purple"]
for i in range(4):
    turtle.pencolor(colors[j % 7])
    turtle.circle(40,180)
    j = j + 1
    turtle.pencolor(colors[j % 7])
    turtle.circle(-40,180)
    j = j + 1
turtle.pencolor('yellow')
turtle.fd(200)
j = 0
for k in range(4):
    turtle.pencolor(colors[j % 7])
    turtle.circle(-40,180)
    j = j + 1
    turtle.pencolor(colors[j % 7])
    turtle.circle(40,180)
    j = j + 1    
turtle.pencolor('yellow')
turtle.circle(-40,180)
turtle.fd(200)
turtle.circle(-40,180)
turtle.done()
