python升国旗代码

以下是 Python 实现的升国旗代码：

import turtle

def draw_rectangle(x, y, width, height, color):
    turtle.up()
    turtle.goto(x, y)
    turtle.fillcolor(color)
    turtle.begin_fill()
    for i in range(2):
        turtle.forward(width)
        turtle.right(90)
        turtle.forward(height)
        turtle.right(90)
    turtle.end_fill()

def draw_star(x, y, radius, color):
    turtle.up()
    turtle.goto(x, y)
    turtle.setheading(0)
    turtle.right(72)
    turtle.fillcolor(color)
    turtle.begin_fill()
    turtle.down()
    for i in range(5):
        turtle.forward(radius)
        turtle.right(144)
        turtle.forward(radius)
        turtle.right(72 - 144)
    turtle.end_fill()

def draw_china_flag(x, y):
    turtle.speed(10)
    turtle.hideturtle()
    turtle.bgcolor('red')

    # 画大矩形
    big_width = 640
    big_height = 400
    draw_rectangle(x, y, big_width, big_height, 'red')

    # 画小矩形
    small_width = 320
    small_height = 200
    draw_rectangle(x, y+140, small_width, small_height, 'yellow')

    # 画星星
    star_x = x + 40
    star_y = y + 320
    radius = 20
    draw_star(star_x, star_y, radius, 'yellow')

    # 画四颗小星星
    gap = 60
    for i in range(4):
        x = star_x + gap * (i+1)
        y = star_y - gap
        draw_star(x, y, radius, 'yellow')

if __name__ == '__main__':
    draw_china_flag(-320, -200)
    turtle.mainloop()

运行代码后，会看到窗口里绘制了一面中国国旗。
