1、画一组同切圆
>>> import turtle
>>> turtle.circle(50)
>>> turtle.circle(80)
>>> turtle.circle(100)
>>> turtle.circle(60)
>>> turtle.circle(70)
>>> turtle.circle(90)
2、画一组同心圆
>>> import turtle
>>> turtle.up()
>>> turtle.goto(0,-10)
>>> turtle.down()
>>> turtle.circle(10)
>>> turtle.up()
>>> turtle.goto(0,-30)
>>> turtle.down()
>>> turtle.circle(30)
>>> turtle.up()
>>> turtle.goto(0,-50)
>>> turtle.down()
>>> turtle.circle(50)
3、画一个五角星
>>> import turtle
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
4、画一个黄色实心五角星
>>> import turtle
>>> turtle.color(‘yellow‘)
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
>>> turtle.right(144)
>>> turtle.forward(50)
>>> turtle.fillcolor(‘yellow‘)
