turtle库基础练习

1. 画一组同心圆

   import turtle
   >>> turtle.circle(20)
   >>> turtle.pos()
   (-0.00,0.00)
   >>> turtle.up()
   turtle.goto(-0,-10)
   >>> turtle.down()
   >>> turtle.circle(30)
   >>> turtle.up()
   >>> turtle.goto(-0,-10)
   >>> turtle.goto(-0,-20)
   >>> turtle.down()
   >>> turtle.circle(40)

   

    

2. 画一组同切圆

    turtle.circle(20)
    turtle.circle(30)
    turtle.circle(40)

   

    

3. 画一个五角星

   turtle.forward(100)
   >>> turtle.left(144)
   >>> turtle.forward(100)
   >>> turtle.left(144)
   >>> turtle.forward(100)
   >>> turtle.left(144)
   >>> turtle.forward(100)
   >>> turtle.left(144)
   >>> turtle.forward(100)

   

    

4. 画一个黄色实心五角星

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