python爱心代码

前言

俺又来啦！大家肯定是满世界找电视剧同款爱心代码，我看很多都是HTML，but！为了不是太过于跟风！so！整一个python同款也是可以的啦！

(记得!!!!一定要安装一个python环境,去下载一个pycharm,可以从b站看怎么下载和配置变量名,还要记得下载相应的库!)

代码来啦!!!

(对了对了！复制完一定要看看下面的总结喔！！！)

总结

注释：代码的第十二行' '里可以写她的名字啦!

大家一定要珍惜自己的女朋友啦，一个人和另一人相遇可能性是千万分之一，成为朋友是两亿分之一，一个人要爱上另一个人的概率是五亿分之一，而如果要成为伴侣，概率是十五亿分只一。如果要白头偕老的话，需要花费二十多年的时间等待，还得用六七十年的时间来完成。一个人对另一个人说一声“我爱你”，需要消耗两个苹果所提供的热量。这一切都显得那么不简单。

所以！！！！！给自己的女友写代码的朋友！一定得给我对她好！要不然！诅咒你这辈子再也碰不到比她好的女孩子啦！！！！！
