python粒子圣诞树代码

以下是一个使用Python绘制粒子圣诞树的代码示例：

import turtle
from random import randint

# 设置画布和画笔
screen = turtle.Screen()
screen.bgcolor("black")
screen.title("Particle Christmas Tree")
pen = turtle.Turtle()
pen.speed(0)
pen.color("white")
pen.pensize(2)
pen.hideturtle()

# 定义函数：绘制雪花
def draw_snow():
    pen.penup()
    pen.goto(randint(-248, 248), randint(-100, 248))
    pen.pendown()
    petal_number = 6
    snow_size = int(randint(2, 10))
    for _ in range(petal_number):
        pen.forward(snow_size)
        pen.backward(snow_size)
        pen.right(360 / petal_number)

# 绘制圣诞树
def draw_tree():
    pen.penup()
    pen.goto(0, -200)
    pen.pendown()
    pen.color("green")
    pen.begin_fill()
    pen.left(90)
    pen.forward(200)
    pen.right(135)
    pen.forward(280)
    pen.left(135)
    pen.forward(280)
    pen.right(135)
    pen.forward(200)
    pen.end_fill()

# 绘制粒子
def draw_particles():
    pen.penup()
    pen.goto(0, 100)
    pen.pendown()
    pen.color("yellow")
    pen.begin_fill()
    pen.circle(20)
    pen.end_fill()

# 调用函数绘制圣诞树和粒子
draw_tree()
draw_particles()

# 绘制雪花
for _ in range(80):
    draw_snow()

# 结束绘制
turtle.done()
