Python turtle库小练习

问题1:利用Turtle库画出奥运五环

#画一个奥运五环
#黑色圆环
import turtle
turtle.speed(10)
turtle.up()
turtle.goto(50,0)
turtle.down()
turtle.pensize(8)
turtle.circle(100)
#蓝色圆环
turtle.up()
turtle.goto(-170,0)
turtle.down()
turtle.pencolor("blue")
turtle.circle(100)
#红色圆环
turtle.up()
turtle.goto(270,0)
turtle.down()
turtle.pencolor("red")
turtle.circle(100)
#绿色圆环
turtle.up()
turtle.goto(160,-120)
turtle.down()
turtle.pencolor("green")
turtle.circle(100)
#黄色圆环
turtle.up()
turtle.goto(-60,-120)
turtle.down()
turtle.pencolor("yellow")
turtle.circle(100)
turtle.done()

 运行结果如下

问题2：画出一个红色五角星 

import turtle
turtle.pensize(3)
turtle.begin_fill()
turtle.fillcolor("red")
turtle.left(72)
turtle.forward(200)
turtle.right(144)
turtle.forward(200)
turtle.left(72)
turtle.forward(200)
turtle.right(144)
turtle.forward(200)
turtle.left(72)
turtle.forward(200)
turtle.right(144)
turtle.forward(200)
turtle.left(72)
turtle.forward(200)
turtle.right(144)
turtle.forward(200)
turtle.left(72)
turtle.forward(200)
turtle.right(144)
turtle.forward(200)
turtle.end_fill()
turtle.hideturtle()
turtle.done()

 运行结果如下：
