Python turtle库绘制五星红旗

直接上代码

import turtle

"""
五星红旗的宽高比是3:2，这里我们使用300x200的大小作为红旗底部
5颗黄色的星星，1颗大星星，4颗小星星
"""

def main():
    turtle.setup(500, 500, 200, 200)
    drawBackground()
    drawBigStar()
    drawSmallStar(-50, 170, 30)
    drawSmallStar(-30, 145, 25)
    drawSmallStar(-30, 117, 15)
    drawSmallStar(-47, 95, 25)
    turtle.hideturtle()
    turtle.done()

    # 调整画笔的位置
    turtle.penup()
    turtle.setpos(-150, 0)
    # 绘制并填充
    turtle.pencolor('red')
