使用Python画旗台上飘扬的五星红旗

使用Python画五星红旗可以通过turtle库实现，以下是实现的代码示例：

import turtle

# 定义红色矩形
def draw_rectangle(x, y, width, height):
    turtle.penup()
    turtle.goto(x, y)
    turtle.color('red', 'red')
    turtle.begin_fill()
    for i in range(2):
        turtle.forward(width)
        turtle.left(90)
        turtle.forward(height)
        turtle.left(90)
    turtle.end_fill()

# 定义一个五角星
def draw_star(x, y, radius):
    turtle.setpos(x, y)
    # 计算五个顶点的坐标
    pt1 = turtle.pos()
    turtle.circle(-radius, 72)
    pt2 = turtle.pos()
    turtle.circle(-radius, 72)
    pt3 = turtle.pos()
    turtle.circle(-radius, 72)
    pt4 = turtle.pos()
    turtle.circle(-radius, 72)
    pt5 = turtle.pos()
    # 画五角星
    turtle.color('yellow', 'yellow')
    turtle.begin_fill()
    turtle.goto(pt3)
    turtle.goto(pt1)
    turtle.goto(pt4)
    turtle.goto(pt2)
    turtle.goto(pt5)
    turtle.end_fill()

# 主函数
def main():
    # 设置初始位置和朝向
    x, y = -270, 200
    turtle.speed(10)
    turtle.hideturtle()
    # 画国旗主体
    draw_rectangle(x, y, 540, 360)
    # 画大星星
    draw_star(x+60, y-30, 30)
    # 画小星星
    draw_star(x+180, y-60, 15)
    draw_star(x+180, y-150, 15)
    # 画小小星星
    draw_star(x+120, y-90, 10)
    draw_star(x+240, y-90, 10)
    draw_star(x+300, y-120, 10)
    draw_star(x+300, y-210, 10)

if __name__ == '__main__':
    main()
