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

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。

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。

总结

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~
