python圣诞树高级

以下是一个高级的Python圣诞树绘制的例子：

import turtle

def draw_tree(d, s):
    if d <= 0:
        turtle.forward(s)
        return
    
    draw_tree(d - 1, s * 0.8)
    turtle.right(120)
    draw_tree(d - 3, s * 0.5)
    draw_light()
    turtle.right(120)
    draw_tree(d - 3, s * 0.5)
    turtle.right(120)
    turtle.backward(s)

def draw_light():
    # 绘制小彩灯的代码
    pass

def draw_leaves():
    # 绘制圣诞树的落叶的代码
    pass

def draw_gifts():
    # 绘制圣诞节礼物的代码
    pass

def draw_snowflakes():
    # 绘制漫天雪花的代码
    pass

def draw_christmas_tree():
    turtle.begin_fill()
    turtle.right(126)
    turtle.color("dark green")
    turtle.backward(n * 4.8)
    draw_tree(15, n)
    turtle.backward(n/2)
    draw_leaves()
    draw_gifts()
    draw_snowflakes()
    turtle.end_fill()

# 设置海龟绘图的参数
turtle.setup(800, 600)
turtle.speed(0)
turtle.penup()
turtle.goto(-200, -200)
turtle.pendown()

# 绘制圣诞树
n = 100
draw_christmas_tree()

# 关闭海龟绘图窗口
turtle.done()
