画国旗代码

import turtle


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

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

turtle.setup(600, 400)
turtle.color("yellow")
turtle.bgcolor("red")
turtle.fillcolor("yellow")

mygoto(-110,150)
drawsatr(40)

mygoto(-70,100)
drawsatr(40)

mygoto(-70,50)
drawsatr(40)

mygoto(-110,0)
drawsatr(40)
