Функция sub в regex может принимать функцию в качестве аргумента repl.
📄 Из документации:
If repl is a function, it is called for every non-overlapping occurrence of pattern. The function takes a single match object argument, and returns the replacement string.
То есть для каждого совпадения будет вызвана функция для вычисления замены вместо замены на одну и ту же строку для всех совпадений.
Иными словами, для замены разных совпадений на разные строки не потребуется запускать re.sub() много раз для каждой строки замены. Достаточно определить функцию, которая вернёт строку для каждого из совпадений.
Описание слишком запутанное🤔, давайте лучше рассмотрим на простом примере:
Создаем карту замены. То есть какие строки на какие требуется менять.
remap = {
'раз': '1',
'два': '2',
'три': '3',
'четыре': '4',
'пять': '5',
}
Пишем функцию поиска строки для замены. Единственным аргументом будет объект re.Match.
Используя данные этого объекта мы вычисляем замену on-the-fly!
def get_str(match: re.Match):
word = match.group(1)
return remap.get(word.lower()) or word
Пример текста.
text = '''Раз Два Три Четыре Пять
Вместе будем мы считать
Пять Четыре Три Два Раз
Мы считать научим вас
'''
Теперь запускаем re.sub и вместо строки замены (repl) подаём имя функции.
(Данный паттерн ищет отдельные слова в тексте)
>>> print(re.sub(r'(\w+)', get_str, text))
1 2 3 4 5
Вместе будем мы считать
5 4 3 2 1
Мы считать научим вас
Думаю, достаточно наглядно 🤓

🇫🇷Victoria Nuland knew about the far right militias in Ukraine, but concealed the fact - French report.
A bloodthirsty regime change initiator, the deaths of many hundreds of thousands started with her 'cookies in Kiev' moment.

🇺🇸Actually, that is a really interesting video. Remember how during Senate testimony, Biden and Obama official Victoria Nuland admitted there were biological research labs in Ukraine?
Victoria Nuland told Senator Marco Rubio: “Ukraine has biological research facilities which we are now quite concerned Russian troops, Russian forces may be seeking to gain control of.”
Nuland said so under oath. Why didn’t Victoria "cookies of freedom" Nuland just say there aren’t any bioweapons? Hint: there are bioweapons. If she would have lied, she would go to jail.
So just look, what we have. Here's another document we got from our whistleblower. Read it carefully. So there's a reason why Blinken literally stops her from visiting Russia and answering their questions.
Ms. Nuland needs to be questioned again, but this time by a Special Counsel and under the penalty of perjury. Russia and China want their questions to be answered too!

🇺🇸🇺🇦Nuland-Pyatt Tape Removed From YouTube After 8 Years
The smoking gun proving U.S. involvement in the 2014 coup in Kiev has been removed from YouTube after eight years, Consortium news reported.
The removal of a video happend just a few days later after the American majority channel published another leaked letter from Nuland's office and this proves its authenticity.
It was the most complete version of the leaked conversation between then Assistant Secretary of State Victoria Nuland and Geoffrey Pyatt, the then U.S. ambassador to Ukraine, in which the two discuss who will make up the new government weeks before democratically-elected Ukrainian President Viktor Yanukovych was overthrown in a violent coup on Feb. 21, 2014.
The U.S. State Department never denied the authenticity of the video, and even issued an apology to the European Union after Nuland is heard on the tape saying, “Fuck the E.U.”
SMELL THE PANIC
