python制作动态圣诞树

以下是使用turtle库制作动态圣诞树的Python代码：

import turtle
import random

# 设置画笔
turtle.speed(0)
turtle.hideturtle()
turtle.pensize(2)

# 定义绘制圣诞树的函数
def drawTree(x, y, size):
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.setheading(90)
    turtle.color("green")
    turtle.begin_fill()
    turtle.forward(size)
    turtle.right(90)
    turtle.forward(40)
    turtle.right(90)
    turtle.forward(size)
    turtle.end_fill()
    if size > 20:
        drawTree(x + 20, y + 40, size * 0.7)
        drawTree(x - 20, y + 40, size * 0.7)
        drawTree(x, y + 60, size * 0.7)

# 定义绘制雪花的函数
def drawSnow():
    turtle.hideturtle()
    turtle.speed(0)
    turtle.pencolor("white")
    turtle.pensize(2)
    for i in range(80):
        turtle.penup()
        turtle.goto(random.randint(-248,248), random.randint(-100, 248))
        turtle.pendown()
        petalNumber = 6
        snowSize = int(random.randint(2, 10))
        for j in range(petalNumber):
            turtle.forward(snowSize)
            turtle.backward(snowSize)
            turtle.right(360 / petalNumber)

# 绘制圣诞树和雪花
drawTree(0, -200, 100)
drawSnow()

# 显示画布
turtle.done()
