turtle库基础练习

1 画一组同切圆

>>> import turtle
>>> turtle.circle(10)
>>> turtle.circle(30)
>>> turtle.circle(50)
>>> turtle.circle(70)
>>> 

　　

2、画一组同心圆

import turtle
>>> turtle.up()
>>> turtle.goto(0,-20)
>>> turtle.down()
>>> turtle.circle(20)
>>> turtle.up()
>>> turtle.goto(0,-30)
>>> turtle.down()
>>> turtle.circle(30)
>>> turtle.up()
>>> turtle.goto(0,-40)
>>> turtle.down()
>>> turtle.circle(40)

>>>turtle.done()

　　

3、画一个五角星

>>> turtle.speed(1)
>>> tuetle.forward(100)
>>> 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.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()
>>> turtle.hideturtle()
>>> turtle.done()
