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()

🎊🎉🍾🇳🇬🇷🇺
Our beloved organisation, NIDO Russia has been officially accepted as a full member of NIDO Europe yesterday evening 01.02.2025 by the overwhelming majority of the general house which is the supreme organ. We owe this success to our faithful members, the board of trustees, the chairmen Emeritus and stakeholders.
Recall that, a tiny group of people prevented this for many years, saying that we must be part of their cabal for our rights to be respected in Europe. We rejected their ideas and protocols, we refused to be gradually assimilated, we took our destiny in our hands, knowing God was on our side. Their condition for peace was that we stoop low and be under them. We rejected that kind of parasitic peace. This group said it was either their way or the highway. We chose the beautiful highway. You must not be a doctor or lawyer or teacher to be part of NIDO Russia or NIDO Europe. Every Nigerian legally residing in Russia has a right to apply to be part of us. Even those who may not yet be fully legal, it is not our duty to judge or condemn them, but rather to guide them (socioeconomically adapt them) towards legalisation and contributing positively to Russia and their families in Nigeria.
It is a huge lesson for us all. "Na who give up, na him lose".
Nevertheless, we are open to working together with everyone for our common good including those few people who worked against us. It is a new era.
What are the benefits of being part of NIDO Europe?
1. The interests of Nigerians in Russia can be represented on a continental level.
2. The interests of the Russian Federation which are also our interests as residents can be represented on a continental level
3. Better negotiating power with the government on matters important to us as Diasporans.
4. Better synergy of efforts towards national development, bilateral trade, foreign direct investments and human capital development.
I, on behalf of the executives congratulate us all for this huge achievement including those members who witnessed it live and direct.
Yours in service,
Dr. Godwin Ibe
