python粒子圣诞树

以下是一个使用Python绘制粒子圣诞树的例子：

import turtle
from random import randint

# 设置画布
turtle.setup(800, 600)
turtle.bgcolor("black")

# 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): # 雪花数量
        turtle.goto(randint(-248, 248), randint(-100, 248))
        petalNumber = 6 # 雪花花瓣数为6
        snowSize = int(randint(2, 10))
        
        for j in range(petalNumber):
            turtle.fd(snowSize)
            turtle.backward(snowSize)
            turtle.right(360/petalNumber)

# 绘制圣诞树
