前言

最近那个电视剧很火，就是搞爱心代码的，本人兴趣使然，在网上搜集了一些代码，经过一定修改，做一个小总结。源文件直接免费下载点此处

一、python

运行

主要用的包都是那么几个，csdn搜pycharm怎么导包就可以。

调整思路

HEART_COLOR = “#EEAEEE” #引号内修改颜色！颜色代码放在文章末尾

双引号里面可以在csdn搜RGB颜色，比如这个兄弟的，直接看里面的对照表，把包括#的数字或字母替换就可以换颜色了

代码如下

二、HTML

html的个人感觉更好，因为有浏览器就支持运行，py的后期得导出成exe才可以在没有环境设备运行，html手机电脑都可以的。

调整

这个canvas爱心字样随便调整可以自己编辑TA的名字之类的

代码如下

html, body {  height: 100%;  padding: 0;  margin: 0;  background: #000;}canvas {  position: absolute;  width: 100%;  height: 100%;}/* * Settings */var settings = {  particles: {    length:   500, // maximum amount of particles    duration:   2, // particle duration in sec    velocity: 100, // particle velocity in pixels/sec    effect: -0.75, // play with this for a nice effect    size:      30, // particle size in pixels  },};/* * RequestAnimationFrame polyfill by Erik M" />

这个我个人感觉还是蛮好看的，值得注意的是，里面的字是也能动的，可以把♥瓜瓜♥改成你想要的字眼（代码里面ctrl+f 找瓜瓜字眼 替换即可），titile也同理

3.第四个html
样例
代码调整思路
x位置直接记事本打开ctrl+f 找亲爱的 编辑文案
然后对这行字的编辑（样式上）
是这个，改这里的信息就行哪个参数不会就搜一下他的作用 比如第一行是字体，你可以百度html字体比如这个大佬写的博客，都是一样道理。

本文简单介绍了几种爱心代码，希望对大家有所帮助，求赞欧~~~
 另外，python想送给你的那个TA的话可以打包为exe的，我后期再补一下教程，然后运行有问题的可以在评论区说明~
