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()

Taiwan's Gold Apollo pager company issued a statement stating:
"- The #pagers that exploded in #Lebanon carry our trademark, but they were manufactured in Europe.
- All AP924 Model Pager models were subcontracted to a company in Europe, about 5,000 in that batch to Lebanon.
- The pagers were manufactured in through third party components."
They are trying to clear Taiwan, which is mostly plausible, as Europe was always the hub for the Mossad historically when sabotaging supply chains.
How about naming the European country/manufacturer? Wouldn't that clear the Taiwan based company's name faster?
AP-900: This what we know about one of the #pagers that exploded in #Lebanon at the hands of Zionist Israel:
▫️The AP-900 alphanumeric pager functions as a wireless communication device that receives messages via radio signals.
▫️At least 11 people have been martyred and over 4,000 others, including civilians, medics and Hezbollah members, were injured when their paging devices exploded across Lebanon.
▫️The AP-900, popular in the 1990s and early 2000s, was designed to receive and display text messages, making it an essential communication tool in various professional and emergency settings.
▫️Despite its simplicity, the AP-900 operates on a sophisticated system that ensures messages are delivered promptly and accurately.
▫️A message transmission starts at a central paging terminal, which encodes the message into a signal format like FLEX or POCSAG.
▫️This signal is sent over a specific frequency band, and the AP-900 pager, scanning for signals that match its unique identifier, receives it through its antenna.
▫️The pager then decodes and displays the message on its screen, alerting the user with vibration, sound, or both.
▫️Additionally, the AP-900 can store multiple messages for later review.
▫️Can the AP-900 Be Hacked?
Theoretically, yes, the AP-900 can be hacked, but it would require specialised knowledge and equipment, information from open sources show.
▫️Although the messages are encoded, they are not typically encrypted, meaning that an intercepted message can be easily decoded.
▫️More sophisticated attacks could involve compromising the messaging infrastructure or physically tampering with the devices during distribution.
AP-900 and AR-924 pagers were the latest tool of Israeli attacks against Lebanon. A massive terrorist attack saw the devices exploding among civilians and Hezbollah members in a Mossad-operated aggression.
