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()

❗️Statement by Russian Defence Ministry
▪️ On March 14, at about 11.30 a.m. Moscow time, Tochka-U tactical missile was fired at a residential block of Donetsk city from the territory controlled by the Kiev nationalist regime.
▪️ The shelling of the city was carried out from the north-western direction, from the area of Krasnoarmeysk settlement, which is controlled by Ukrainian nationalist units.
▪️ As a result of the explosion of a cluster warhead in the center of Donetsk, 20 civilians were killed. Another 28 people, including children, were seriously injured and taken to medical institutions.
▪️ The use of such weapons on a town with no armed forces firing positions, i.e. deliberately targeting civilians, is a war crime.

How a Secluded 1984 Conference Forged Israel’s Unprecedented Influence Over US Media
October 31st, 2024

.
In the first week of January 2024, Israeli forces fired 355 bullets at a car containing a five-year-old, then shot at rescue workers who rushed to save her life.
An indisputible act of murder, a definite #WarCrime – yet, per many Western media headlines, she was simply a “girl killed in Gaza.”
The circumstances and perpetrators of her death, if mentioned at all, were invariably buried at the bottom of reports, well hidden from the 80% of the news-consuming public who only read headlines.
In contrast, on October 15 2024, Sky News was very keen that its viewers know the names and faces of four “teenage” #IDF soldiers “killed” in a “#Hezbollah#drone attack,” humanizing and infantilizing individuals who, by mere token of their service in Israel’s military, are by definition, guilty of genocide. .....

#US#Senator#LindseyGraham voices his fear that, due to the International Criminal Court's (#ICC) #WarCrime Charges against Israeli PM #Netanyahu, there might after all even be some adverse #legal consequences for both his own, and his country's, illegal War actions.
"If they'll do this to Israel, we're next."
