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 🤓

#Venezuela
La Presidente ad interim Delcy #Rodríguez (#PSUV|Estrema sinistra) ha annunciato la presentazione di una legge di amnistia generale per tutti i prigionieri politici del Paese che dovrebbe “coprire l’intero periodo di violenza politica dal 1999 al presente”.
"Questa legge servirà a sanare le ferite lasciate dal confronto politico, alimentato dalla violenza e dall'estremismo. Ci permetterà di rimettere in carreggiata la giustizia nel nostro Paese", annunciando inoltre “un'importante consultazione nazionale per un nuovo sistema giudiziario" e l’intenzione di chiudere il carcere di El Helicoide a Caracas, ove per i gruppi per i diritti umani venivano imprigionati e torturati i prigionieri politici, per trasformarlo in un “entro sportivo, culturale e commerciale per le famiglie dei poliziotti e le comunità limitrofe”.

📰CIA Director Ratcliffe Meets Venezuela’s Interim President in Caracas
CIA Director John Ratcliffe met with Delcy Rodríguez, Venezuela’s interim president, in Caracas on Thursday—marking the highest-level U.S. visit since the dramatic U.S. military operation that captured President Nicolás Maduro nearly two weeks ago. Ratcliffe’s trip was directed by President Trump to signal that the U.S. sees Rodríguez’s interim government as the best path to stability in the short term, despite opposition frustration over the lack of a quick transition to María Corina Machado’s camp.
Stability Over Revolution
The meeting focused on intelligence cooperation, economic stability, and ensuring Venezuela is no longer a “safe haven for America’s adversaries, especially narco-traffickers.” U.S. officials emphasized that breaking up the Venezuelan government after Maduro’s removal could trigger chaos similar to the kind of chaos that followed the Iraq invasion. CIA analysts reportedly see Rodríguez as a pragmatic, rather than ideological, figure willing to negotiate with Washington.
Behind the Scenes: Pragmatism and Power
Rodríguez, Maduro’s former vice president, has shifted her rhetoric, publicly inviting the U.S. to cooperate. But Trump has warned that if she fails to comply, her fate could be worse than Maduro’s. The administration is clear: the U.S. will “run” Venezuela until a safe transition is possible, prioritizing control over oil and security assets above all else.
Protests and Uncertain Alliances
With ongoing protests in Venezuela, the opposition remains sidelined, and the U.S. is betting on Rodríguez to maintain order. But questions linger: How long will this uneasy alliance last? And will the U.S. eventually let democracy take its course—or keep pulling the strings?
