本文通过Python的Turtle库详细介绍了如何绘制五角星、同心圆、太阳花等几何图形，提供了完整的代码示例，适合初学者快速掌握Turtle绘图技巧。

画五角星

import turtle

turtle.color('yellow')
turtle.bgcolor('red')
turtle.fillcolor('yellow')

def lh_star(r):
    turtle.begin_fill()
    for i in range(5):
        turtle.forward(r)
        turtle.right(144)
    turtle.end_fill()

lh_star(150)

画同心圆

import turtle
for i in range(5):
    turtle.up()
    turtle.goto(0,-20*(i+1))
    turtle.down()
    turtle.circle(20+20*(i+1))

画太阳花

import  turtle
turtle.color('black')
turtle.fillcolor('red')
turtle.begin_fill()
while True:
    turtle.forward(200)
    turtle.left(170)
    if(abs(turtle.pos()))<1:
        break
turtle.end_fill()

画五个五角星

import turtle

turtle.color('yellow')
turtle.bgcolor('red')
turtle.fillcolor('yellow')

def lh_goto(x,y):
    turtle.up()
    turtle.goto(x,y)
    turtle.down()

def lh_star(r):
    turtle.begin_fill()
    for i in range(5):
        turtle.forward(r)
        turtle.right(144)
    turtle.end_fill()

lh_goto(-275,175)
lh_star(100)

lh_goto(-175,50)
lh_star(50)

lh_goto(-100,100)
lh_star(50)

lh_goto(-100,175)
lh_star(50)


lh_goto(-170,250)
lh_star(50)

turtle.hideturtle()

画◇花瓣的太阳花

import  turtle
turtle.color('white')
turtle.bgcolor('black')
turtle.speed(10)
def lh_ling(a):
    for i in range(2):
        turtle.forward(a)
        turtle.right(30)
        turtle.forward(a)
        turtle.right(150)

for i in range(36):
    lh_ling(50)
    turtle.left(170)

turtle.goto(0,-150)
turtle.hideturtle()
