本文主要是介绍理工男李峋的极致浪漫：爱心代码｜和你的心跳同频共振，HTML版本和Python版本，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、写在前面的话
最近随着电视剧《点燃我温暖你》的火热播出，剧中帅气学霸李洵的炫酷爱心代码也迅速火出了圈，作为一个喜欢动手实践的我来说正是一个大好机会啊，来看效果和代码部分，本文介绍了HTML和python爱心。
二、先来看Html的爱心吧
遇事先不慌先来看效果图。音乐、文字和爱心大小可以随意改动
（1）效果图
（2）废话不多说直接上代码

三、Python实现爱心代码
画爱心用到一个数学函数，再用一个python的 tkinter 库，也就是GUI图形界面。在代码20行
各种常见颜色的RGB数值|RGB数值,rgb颜色表,金色rgb,rgb颜色,rgb颜色代码,各种颜色的rgb,常用颜色rgb,金属颜色rgb,rgb颜色对照表这里学习分享网站优化知识、网站优化文章、网站优化技巧、网站优化方法等..http://www.ilikeseo.cn/wangzhanyingxiaozhishi_30.html20行这里 HEART_COLOR = "#ff1943" 可以自行更改颜色，颜色用网络编码，更多颜色看上面这个链接。
（1）废话不多说直接看效果
动态爱心，颜色大小自行改动
（2）来吧、代码展示

先预祝表白成功。如果python代码运行不出来，有什么问题或者需要下载源码请看博主首页。最后实在不能运行python可以直接下载python可执行文件.exe。
