python高级爱心代码实现：

import turtle
import random

# 设置画布
screen = turtle.Screen()
screen.bgcolor("black")

# 创建画笔
pen = turtle.Turtle()
pen.speed(0)
pen.color("red")
pen.penup()

# 移动画笔到起始位置
pen.goto(0, -200)
pen.pendown()

# 开始绘制爱心
pen.begin_fill()
pen.left(140)
pen.forward(224)
for _ in range(200):
    pen.right(1)
    pen.forward(2)
pen.left(120)
for _ in range(200):
    pen.right(1)
    pen.forward(2)
pen.forward(224)
pen.end_fill()

# 添加闪烁特效
pen.penup()
pen.color("yellow")
pen.goto(0, -100)
pen.pendown()
pen.begin_fill()
pen.circle(10)
pen.end_fill()

for _ in range(20):
    x = random.randint(-300, 300)
    y = random.randint(-300, 300)
    pen.penup()
    pen.goto(x, y)
    pen.pendown()
    pen.begin_fill()
    pen.circle(random.randint(1, 5))
    pen.end_fill()

# 隐藏画笔
pen.hideturtle()

# 关闭绘图窗口
turtle.done()
