中国情人节
七夕节，又称“七巧节”“女儿节”“乞巧节”等，是中国民间的传统节日。这个节日被赋予了“牛郎织女”的美丽爱情传说，被认为是中国最具浪漫色彩的传统节日，在当代更是产生了“中国情人节”的文化含义。
一年一度的七夕又快到了，我发现网上有很多写得很好的Python表白代码，感觉绘出来的图很漂亮。
我整理了一下，挑了一些我觉得不错的代码和部分自认不错的原创分享给大家。
这些我都测试过，确实可以生成喔~，选一种喜欢的方式发给你的那个TA吧。
更多原创表白代码：比心、永恒心动、我的眼里只有你、表白烟花、这是我的某某某见本文最后的文章链接。
可以边听音乐边看Python代码图。
一、入门级
1. 一行代码画爱心
代码语言：javascript复制print('\n'.join([''.join([('Love'[(x-y)%4]if((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3<=0 else' ')for x in range(-30,30)])for y in range(15,-15,-1)]))效果图
