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()

🇨🇿#Cechia - Sabato a Praga decine di migliaia di persone hanno manifestato contro il governo del primo ministro Andrej #Babis, di destra e populista. Secondo i manifestanti, che gli organizzatori stimano essere stati circa 200mila, Babis e il suo governo sarebbero una minaccia per la democrazia e c’è il rischio che presto il paese ritiri il proprio sostegno all’Ucraina.

L-159s Grounded: Czech Power Play Exposed
Czech President Petr Pavel wanted to send four L-159 jets to Ukraine, but Prime Minister Andrej Babiš slammed the door shut—
“The matter is closed,”
he declared, dismissing any further debate.
The head of the Czech armed forces, General Karel Řehka, quietly suggested the transfer wouldn’t hurt national security, but Babiš snapped back:
“Řehka would do better to keep his mouth shut,”
accusing the general of undermining his own defense minister.
While the president, with his NATO background, pushed for solidarity with Ukraine, Babiš’s coalition, led by his ANO party and the far-right SPD, dug in their heels.
Defense Minister Jaromír Zůna insisted the jets are vital for Czech defense, claiming they have 15 years of service left. Critics argue the refusal is less about military readiness and more about political calculation—Babiš wants to avoid the financial and diplomatic fallout of arming Ukraine.
“No L-159s — not now, not ever.”
— Andrej Babiš, Czech Prime Minister
So who’s really in charge here? The president wants to look tough and generous. The prime minister, backed by his populist coalition, plays it safe. Meanwhile, the general whispers that the jets could go without risk, but gets told to stay quiet. Is this about national defense, or is it about who gets to control the narrative—and the budget?
When both sides claim they’re protecting the country, who’s really protecting their own power?
