帮我写python的代码实现画国旗

好的，以下是一个简单的 Python 代码实现画中国国旗的例子：

import turtle

# 画矩形
def draw_rectangle(x, y, width, height):
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color('red')
    turtle.forward(width)
    turtle.right(90)
    turtle.forward(height)
    turtle.right(90)
    turtle.forward(width)
    turtle.right(90)
    turtle.forward(height)
    turtle.right(90)
    turtle.end_fill()

# 画五角星
def draw_star(x, y, radius):
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.begin_fill()
    turtle.color('yellow')
    turtle.right(72)
    for i in range(5):
        turtle.forward(radius)
        turtle.right(144)
        turtle.forward(radius)
        turtle.right(72)
    turtle.end_fill()

# 画国旗
def draw_flag():
    turtle.speed(0)
    turtle.hideturtle()
    # 画大矩形
    draw_rectangle(-300, 150, 600, 400)
    # 画小矩形
    draw_rectangle(-300, 150, 200, 133)
    # 画五颗大星星
    positions = [(-170, 80), (-100, 100), (-100, 30), (-70, 0), (-10, 0)]
    for position in positions:
        x, y = position
        draw_star(x, y, 30)
    # 画四颗小星星
    positions = [(-140, 55), (-40, 55), (-90, 25), (-40, -5)]
    for position in positions:
        x, y = position
        draw_star(x, y, 15)


# 主函数
def main():
    draw_flag()
    turtle.done()

if __name__ == '__main__':
    main()

运行代码后，会弹出一个窗口，显示出画好的中国国旗。你可以尝试修改代码来画出不同的国旗。
