我要精美炫酷的圣诞树代码编程python

以下是一个用Python编写的精美炫酷的圣诞树代码示例：

import turtle
import random

# 设置画布和画笔
canvas = turtle.Screen()
canvas.bgcolor("black")
pen = turtle.Turtle()
pen.speed(0)
pen.color("white")

# 绘制圣诞树
def draw_tree(branch_len, pen_size):
    if branch_len < 5:
        return
    else:
        pen.pensize(pen_size)
        pen.forward(branch_len)
        pen.left(30)
        draw_tree(branch_len - random.randint(5, 15), pen_size - 1)
        pen.right(60)
        draw_tree(branch_len - random.randint(5, 15), pen_size - 1)
        pen.left(30)
        pen.backward(branch_len)

# 绘制星星
def draw_star():
    pen.color("gold")
    pen.penup()
    pen.goto(random.randint(-200, 200), random.randint(100, 200))
    pen.pendown()
    pen.begin_fill()
    for _ in range(5):
        pen.forward(25)
        pen.right(144)
    pen.end_fill()

# 绘制圣诞树装饰
def draw_decorations():
    colors = ["red", "green", "blue", "yellow", "purple", "orange"]
    for _ in range(50):
        pen.penup()
        pen.goto(random.randint(-200, 200), random.randint(-200, 0))
        pen.pendown()
        pen.color(random.choice(colors))
        pen.begin_fill()
        pen.circle(random.randint(1, 5))
        pen.end_fill()

# 主函数
def main():
    pen.penup()
    pen.goto(0, -200)
    pen.pendown()
    pen.left(90)
    draw_tree(100, 10)
    draw_star()
    draw_decorations()
    turtle.done()

# 调用主函数
main()
