圣诞树代码pyhton飘雪花

以下是一个用Python绘制圣诞树并飘雪花的代码示例：

import turtle
import random

# 绘制圣诞树
def draw_tree():
    height = 5
    stars = 1
    for i in range(height):
        print((' ' * (height - i)) + ('*' * stars))
        stars += 2

# 飘雪花
def snowfall():
    turtle.speed(0)
    turtle.penup()
    turtle.goto(-300, 200)
    turtle.pendown()
    turtle.color("white")
    turtle.shape("turtle")
    turtle.shapesize(0.5)
    for _ in range(100):
        x = random.randint(-400, 400)
        y = random.randint(-300, 300)
        turtle.penup()
        turtle.goto(x, y)
        turtle.pendown()
        turtle.forward(10)
        turtle.backward(10)
        turtle.left(90)
        turtle.forward(10)
        turtle.backward(10)
        turtle.right(90)

# 主函数
def main():
    draw_tree()
    snowfall()
    turtle.done()

# 调用主函数
main()
