画一组同切圆 画一组同心圆 画一个五角星 画一个黄色实心五角星>>> turtle.up() >>> turtle.goto(0,-100) >>> turtle.down() >>> turtle.circle(100) >>> turtle.up() >>> turtle.goto(0,-80) >>> turtle.down() >>> turtle.cir

1.画一组同切圆

>>> import turtle
>>> turtle.circle(10)
>>> turtle.circle(15)
>>> turtle.circle(20)
>>> turtle.circle(25)
>>> turtle.circle(30)

2.画一组同心圆

>>> import turtle
>>> turtle.up()
>>> turtle.goto(0,-100)
>>> turtle.down()
>>> turtle.circle(100)
>>> turtle.up()
>>> turtle.goto(0,-80)
>>> turtle.down()
>>> turtle.circle(80)

>>> turtle.up()
>>> turtle.goto(0,-60)
>>> turtle.down()
>>> turtle.circle(60)
>>> turtle.up()
>>> turtle.goto(0,-40)
>>> turtle.down()
>>> turtle.circle(40)

>>> turtle.up()
>>> turtle.goto(0,-20)
>>> turtle.down()
>>> turtle.circle(20)

 

3.画一个五角星

>>> import turtle
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)

4.画一个黄色实心五角星

>>> turtle.color('yellow')
>>> turtle.fillcolor('yellow')
>>> turtle.begin_fill()
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)
>>> turtle.right(144)
>>> turtle.forward(100)
>>> turtle.end_fill()
