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()

Robert Martin is sailing to Gaza aboard the ‘Handala’. He reminds us that breaking Israel’s illegal siege on Gaza is the most important and urgent act that needs to be undertaken today. For Robert, joining the flotilla is a statement to the Palestinian people that they have not been forgotten as they endure a genocide while under brutal occupation - in spite of the consenting and complicit silence of the media and political establishments.
For Robert, joining the flotilla is also a testament to posterity, and to future generations, that there were people who chose to act.
“The world has woken up. Things are changing and I cannot wait for the day that there is a free Palestine.”
Keep ‘Handala’ safe. End Israel’s Siege.

At 70 years old, Vigdis Bjorvand from Norway is sailing to Gaza aboard 'Handala' to help break Israel's illegal siege - a journey she's been waiting for for years. A Palestine activist since 1978, Vigdis says she never wants her grandchild to say, “Grandma, you didn’t do anything.”
She first joined 'Handala' in 2023, which did not manage to sail to Gaza, and tried again with 'Conscience' earlier this year. Now, she’s back on board, determined to deliver aid, medicine and solidarity to Palestinians in Gaza.
As governments remain silent, Vigdis stands with the Palestinian people. Keep Vigdis safe. Keep 'Handala' safe. And help end Israel's illegal siege and genocide of Gaza.

Drones are now regularly flying over the flotilla.
As Yasemin Acar, Steering Committee member of the Global Sumud Flotilla, explains: this surveillance is meant to intimidate and exhaust us. But it only underscores why our mission is urgent.
For Palestinians, drones are not just cameras. They are weapons of war, used daily to surveil, intimidate, and kill. The same technology that terrorizes Gaza is now policing the Mediterranean, turning the sea into a graveyard.
We will not turn back. We continue to Gaza because this is about justice, freedom, and life.
