本文介绍了使用Python的turtle模块绘制不同样式的五角星图案的方法。包括如何设置画布、颜色填充、移动画笔位置以及绘制多组五角星等技巧。

import turtle
turtle.color('yellow')
turtle.bgcolor('red')
turtle.begin_fill()
for i in range(5):
turtle.forward(200)
turtle.right(144)
turtle.end_fill()

import turtle
for i in range(5):
turtle.up()
turtle.goto(0,-20*(i+1))
turtle.down()
turtle.circle(20*(i+1))
turtle.write(10-i)

import turtle

turtle.color('pink','blue')
turtle.begin_fill()
while True:
turtle.forward(200)
turtle.left(170)
if(abs(turtle.pos()))<1:
break
turtle.end_fill()

4.import turtle
turtle.setup(600,400,0,0)
turtle.color("yellow")
turtle.bgcolor("red")
turtle.fillcolor("yellow")
def mygoto(x,y):
turtle.up()
turtle.goto(x,y)
turtle.down()
mygoto(-250,80)
turtle.begin_fill()
for i in range(5):
turtle.forward(100)
turtle.right(144)
turtle.end_fill()
mygoto(-100,150)
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.right(144)
turtle.end_fill()
mygoto(-50,100)
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.right(144)
turtle.end_fill()

mygoto(-75,35)
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.right(144)
turtle.end_fill()
mygoto(-130,-25)
turtle.begin_fill()
for i in range(5):
turtle.forward(50)
turtle.right(144)
turtle.end_fill()
