python學習筆記（三）

畫個奧運五環，以激發學習python之興趣：

import turtle
turtle.width(10)
turtle.color('blue')
turtle.circle(50)
for i in range(2):
    turtle.penup()
    turtle.forward(120)
    turtle.pendown()
    if i%2==0:
        turtle.color('black')
    else:
        turtle.color('red')
    turtle.circle(50)
turtle.penup()
turtle.goto(55,-50)
turtle.pendown()
turtle.color('yellow')
turtle.circle(50)
for i in range(1):
    turtle.penup()
    turtle.forward(120)
    turtle.pendown()
    turtle.color('green')
    turtle.circle(50)
