从网上down了一个《飞鸟集》的txt文件，其内容是这样的

Stray Birds

飞鸟集





1



Stray birds of summer come to my window to sing and fly away. And yellow leaves of autumn, which have no songs, flutter and fall there with a sigh.



夏天的飞鸟，飞到我窗前唱歌，又飞去了。

秋天的黄叶，它们没有什么可唱，只叹息一声，飞落在那里。





2



O troupe of little vagrants of the world, leave your footprints in my words.



世界上的一队小小的漂泊者呀，请留下你们的足印在我的文字里。





3



The world puts off its mask of vastness to its lover. It becomes small as one song, as one kiss of the eternal.



世界对着它的爱人，把它浩瀚的面具揭下了。

它变小了，小如一首歌，小如一回永恒的接吻。





4



It is the tears of the earth that keep her smiles in bloom.



是“地”的泪点，使她的微笑保持着青春不谢。





5



The mighty desert is burning for the love of a blade of grass who shakes her head and laughs and flies away.



广漠无垠的沙漠热烈地追求着一叶绿草的爱，但她摇摇头，笑起来，飞了开去。





6



If you shed tears when you miss the sun, you also miss the stars.



如果错过了太阳时你流了泪，那么你也要错过群星了。





7



The sands in your way beg for your song and your movement, dancing water. Will you carry the burden of their lameness?



跳舞着的流水呀，在你途中的泥沙，要求你的歌声，你的流动呢。你肯挟跛足的泥沙而俱下么？





8



Her wistful face haunts my dreams like the rain at night.



她的热切的脸，如夜雨似的，搅扰着我的梦魂。





9



Once we dreamt that we were strangers. We wake up to find that we were dear to each other.



有一次，我们梦见大家都是不相识的。

我们醒了，却知道我们原是相亲爱的。

总共325段（上面只截取了9段），每天要给女朋友发一段，用邮件的形式。因为是重复性操作，所以诉诸于代码实现。

所以做一个数据处理，用正则表达式把每一段提取出来，写成json文件，格式如下：

{
    "1": "Stray birds of summer come to my window to sing and fly away. And yellow leaves of autumn, which have no songs, flutter and fall there with a sigh.\n\n\n\n夏天的飞鸟，飞到我窗前唱歌，又飞去了。\n\n秋天的黄叶，它们没有什么可唱，只叹息一声，飞落在那里。",
    "2": "O troupe of little vagrants of the world, leave your footprints in my words.\n\n\n\n世界上的一队小小的漂泊者呀，请留下你们的足印在我的文字里。",
    "3": "The world puts off its mask of vastness to its lover. It becomes small as one song, as one kiss of the eternal.\n\n\n\n世界对着它的爱人，把它浩瀚的面具揭下了。\n\n它变小了，小如一首歌，小如一回永恒的接吻。",
    "4": "It is the tears of the earth that keep her smiles in bloom.\n\n\n\n是“地”的泪点，使她的微笑保持着青春不谢。",
    "5": "The mighty desert is burning for the love of a blade of grass who shakes her head and laughs and flies away.\n\n\n\n广漠无垠的沙漠热烈地追求着一叶绿草的爱，但她摇摇头，笑起来，飞了开去。",
    "6": "If you shed tears when you miss the sun, you also miss the stars.\n\n\n\n如果错过了太阳时你流了泪，那么你也要错过群星了。",
    "7": "The sands in your way beg for your song and your movement, dancing water. Will you carry the burden of their lameness?\n\n\n\n跳舞着的流水呀，在你途中的泥沙，要求你的歌声，你的流动呢。你肯挟跛足的泥沙而俱下么？",
    "8": "Her wistful face haunts my dreams like the rain at night.\n\n\n\n她的热切的脸，如夜雨似的，搅扰着我的梦魂。",
    "9": "Once we dreamt that we were strangers. We wake up to find that we were dear to each other.\n\n\n\n有一次，我们梦见大家都是不相识的。\n\n我们醒了，却知道我们原是相亲爱的。"
}

实现

regex101.com，这个网站真是太好用了。

因为我用的是python，进去之后记得选择python，把文件复制进去，就可以编辑正则表达式了。

代码可以点Code Generator生成，不过不太好用，可以作为参照。

代码：

因为正则表达式中的特殊符号会被博客无情转译，所以放图片不放文本了。

顺便记录一下两日期相差天数的代码：

import time
past = time.mktime(time.strptime("2022-06-29 00:00:00","%Y-%m-%d %H:%M:%S"))
now = time.time()
delta_day = int((now-past)/(24*60*60))
print(delta_day)

保存为json文件，中文不乱码

import json
with open("Birds.json",'w',encoding = 'utf-8') as file_obj:
    json.dump(res,file_obj,ensure_ascii=False,indent = 4)
