Небольшой трик с регулярными выражениями который редко вижу в чужом коде. Допустим, вам нужно распарсить простой текст и вытащить оттуда пары имя+телефон. Вернуть всё это надо в виде списка словарей. Возьмем очень простой пример текста. >>> text = ''' >>> Alex:8999123456 >>> Mike:+799987654 >>> Oleg:+344456789 >>> ''' Соответственно, для выделения нужных элементов будем использовать группы. Получится такой паттерн: (\w+):([\d+]+) Как мы будем формировать словарь из найденных групп? >>> import re >>> results = [] >>> for match in re.finditer(r"(\w+):([\d+]+)", text): >>> results.append({ >>> "name": match.group(1), >>> "phone": match.group(2) >>> }) >>> print(results) [{'name': 'Alex', 'phone': '8999123456'}, ...] Можно немного сократить запись используя zip >>> results = [] >>> for match in re.finditer(r"(\w+):([\d+]+)", text): >>> results.append(dict(zip(['name', 'phone'], match.groups()))) Но есть способ лучше! Это именованные группы в regex. Можно в паттерне указать имя группы и результат сразу забрать в виде словаря. >>> for match in re.finditer(r"(?P<name>\w+):(?P<phone>[\d+]+)", text): >>> results.append(match.groupdict()) То есть всё что я сделал, это добавил в начале группы (внутри сбокочек) такую запись: (?P<group-name>...) Теперь найденная группа имеет имя и можно обратиться к ней как к элементу списка >>> name = match['name'] Либо забрать сразу весь словарь методом groupdict() >>> match.groupdict() #tricks#regex

Every day people from all parts of the world would remind me how amazing their lives are and how mine isn't. I notice most of the people around me are just pretending to be happy, they show me what they want me to see not what i'm needed to see. I somehow know the truth but it's just so tough to believe it. It's just that my heart is so used to being sad about every other single situation, now it finds it challenging to become something it has never been. Honestly, my heart gave up on me a long time ago because my dumbass would always try to find reasons to make myself feel like shit. With time I reached a point where I no more cared if I was happy or not.I had no idea about what I was trying to do with myself. I didn't care if I watched that tv show which I used to enjoy, I didn't care if I ate those chicken rolls that my mom prepared just for me because I would beg her to make them, I didn't care if I was healthy, I didn't care about my looks, desires, likes, dislikes. I reached a point where I had no more fucks left with me to give to the world or to myself. During one of the summer holidays my best friend who came to visit me after two whole years would scan my whole appearance with a concerned disgust in his eyes. "Well, you look like shit. I heard from your mom that you haven't eaten anything since last two days. Are you trying to kill yourself or some shit? " I smiled because I finally figured out what I was trying to do with myself.
