用Python画出五星红旗

这是一个用Python绘制五星红旗的示例代码：

import turtle

def draw_rectangle(x, y, width, height):
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.color('red')
    turtle.begin_fill()
    for _ in range(2):
        turtle.forward(width)
        turtle.right(90)
        turtle.forward(height)
        turtle.right(90)
    turtle.end_fill()

def draw_star(x, y, size):
    turtle.penup()
    turtle.goto(x, y)
    turtle.setheading(0)
    turtle.pendown()
    turtle.begin_fill()
    for _ in range(5):
        turtle.forward(size)
        turtle.right(144)
    turtle.end_fill()

def draw_china_flag():
    width, height = 1200, 800
    turtle.setup(width, height)
    turtle.title('China Flag')
    
    # 绘制红色背景
    draw_rectangle(-width/2, height/2, width, -height/2)
    
    # 计算并绘制大星星
    big_star_x, big_star_y = -width/7, height/14
    star_size = height / 10
    draw_star(big_star_x, big_star_y, star_size)
    
    # 计算并绘制小星星
    small_star_size = star_size / 2
    gap = star_size * 2.5
    for row in range(4):
        for col in range(5):
            x = big_star_x + gap * col + gap / 2 * (row % 2)
            y = big_star_y - gap * row
            draw_star(x, y, small_star_size)

    turtle.hideturtle()
    turtle.done()

draw_china_flag()
