這是嵩天老師的python書的習題2.3

#2.3.py
import turtle as t

t.setup(1000,1000)
t.pen(shown = False, pendown = False, pensize = 10, speed = 0)

colorlist = [(255, 0, 0), (255, 165, 0), (255, 255, 0),\
             (0, 255, 0), (0, 255, 255), (0, 0, 255), (139, 0, 255)]
colorlist.reverse()

t.fd(-250)
t.seth(-40)

t.colormode(255)

t.pendown()
for color in colorlist[:-1]:
  t.pencolor(color)
  t.circle(30,80)
  t.circle(-30,80)

t.pencolor(colorlist[-1])
t.circle(30,80/2)
t.fd(40)
t.circle(25,180)
t.fd(40*2/3)
t.done()
