用Python写一个爱心跳动的代码

好的，以下是使用Python的turtle库编写的爱心跳动代码：

import turtle
import math

# 初始化窗口
canvas = turtle.Screen()
canvas.title("爱心跳动")
canvas.bgcolor("black")

# 初始化画笔
pen = turtle.Turtle()
pen.color("red")
pen.shape("turtle")
pen.speed(0)
pen.penup()

# 定义爱心函数
def heart(x, y, size):
    pen.goto(x, y)
    pen.pendown()
    pen.begin_fill()
    pen.fillcolor("red")
    pen.left(45)
    pen.forward(200*size)
    pen.circle(70*size, 180)
    pen.right(90)
    pen.circle(70*size, 180)
    pen.forward(200*size)
    pen.end_fill()

# 定义心跳函数
def heartbeat(x, y, size):
    for i in range(10):
        pen.goto(x, y)
        pen.pendown()
        pen.pensize(3)
        pen.color("red")
        pen.circle(10*size*(1+i/10))
        pen.penup()
        pen.goto(x+20*size*(1+i/10), y)
        pen.pendown()
        pen.circle(10*size*(1+i/10))
        pen.penup()
        pen.goto(x, y)
        pen.pendown()
        pen.pensize(1)
        pen.color("white")
        pen.circle(10*size*(1+i/10))
        pen.penup()
        pen.goto(x+20*size*(1+i/10), y)
        pen.pendown()
        pen.circle(10*size*(1+i/10))
        pen.penup()

# 绘制爱心
heart(0, 0, 1)

# 循环绘制心跳
while True:
    heartbeat(0, 0, 1)
    pen.reset()
    heart(0, 0, 1)

运行代码后，你将看到一个闪烁着红色心形和跳动着的白色圆圈的窗口。
