本文通过Python的turtle模块演示了几何图形的绘制方法，包括同心圆、同切圆及五角星等，并展示了如何填充颜色。

1.画一组同切圆
Python 3.6.2 (v3.6.2:5fd33b5, Jul  8 2017, 04:57:36) [MSC v.1900 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import turtle
>>> turtle.circle(20)
>>> turtle.circle(40)
>>> turtle.circle(60)
>>> turtle.circle(80)
>>>

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) 







1 


>>>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()

5.画左上角的五颗五角星
