python画圣诞树带灯

以下是使用Python绘制带灯的圣诞树的代码示例：

import turtle
import random

# 创建画布
screen = turtle.Screen()
screen.bgcolor("black")

# 创建画笔
t = turtle.Turtle()
t.speed(0)
t.color("green")

# 定义绘制圣诞树的函数
def draw_tree(d, s):
    if d <= 0:
        return
    t.forward(s)
    t.right(120)
    draw_tree(d - 1, s * 0.8)
    t.right(120)
    draw_tree(d - 3, s * 0.5)
    t.right(120)
    draw_tree(d - 3, s * 0.5)
    t.right(120)
    t.backward(s)

# 绘制圣诞树
draw_tree(7, 100)

# 绘制圣诞灯
for i in range(200):
    a = 200 - 400 * random.random()
    b = 10 - 20 * random.random()
    t.up()
    t.forward(b)
    t.left(90)
    t.forward(a)
    t.down()
    if random.randint(0, 1) == 0:
        t.color('red')
    else:
        t.color('yellow')
    t.circle(2)
    t.up()
    t.backward(a)
    t.right(90)
    t.backward(b)

# 隐藏画笔
t.hideturtle()

# 结束绘制
turtle.done()
