drawPython

  1 # drawSnake
  2 import turtle
  3 def drawSnake(rad,angle,len,neckrad):
  4         for i in range(len):
  5                 turtle.circle(rad,angle)
  6                 turtle.circle(-rad,angle)
  7         turtle.circle(rad,angle/2)
  8         turtle.fd(rad)
  9         turtle.circle(neckrad+1,180)
 10         turtle.fd(rad*2/3)
 11
 12 def main():
 13         turtle.setup(1300,800,0,0)
 14         pythonsize=30
 15         turtle.pensize(pythonsize)
 16         turtle.pencolor("blue")
 17         turtle.seth(-40)
 18         drawSnake(40,80,5,pythonsize/2)
 19
 20 main()

效果如下：
