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

It's better to be alone than to be with a bad company. Don't settle for anything less than you deserve. Know your worth 😊 #thoughts#selfreminder @quietworld🍃

Bila kau baru mula bekerja, semalu mana dan serendah diri mana kau rasa pun, anxiety mcm mana pun, beranikan diri bertanya banyak bila tidak tahu sesuatu, itu la privilege jd orang baru. Semalu mana kau rasa untuk bertanya waktu masih baru, bayangkan kalau sudah lama bekerja masih bertanya banyak walaupun berkaitan hal yg lama? Pilih mana satu ☺ #thoughts#selfreminder @quietworld🍃

Quick reminder: don't compare your life to others too much. We grow and learn at different pace. ☺ #thoughts#selfreminder @quietworld🍃

I still have me. Don't lose yourself to anyone. There's no use to have a lot of people in your life at the price of losing yourself – because what's the point of having everyone in your life but not having yourself? Don't be afraid to lose people. Instead, be willing to lose people when you need to. #thoughts#selfreminder @quietworld🍃

Have you ever been in a situation in which you really want to forgive, but your heart can't forgive yet because it still hurts? You really want to forgive but you know you haven't because your heart still aches. & it hurts you more because you still can't forgive. Take your time. Be gentle to your heart. Don't treat your heart like how anyone else treat it. #thoughts#selfreminder@quietworld🍃

Tbh, you don't have to be the most knowledgable person in the world or anywhere. Knowing that you don't know about somethingyou need to know about and able to decide and take action to find out more about it is enough to help you go a long way. It's just that simple. Remember that. #thoughts#selfreminder @quietworld🍃

Don't give more to other people than you give to yourself. Don't be too loyal to other people that you betray yourself. #selfreminder#life @quietworld🍃
