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 🤓

📰 China’s Record Drills: Taiwan Encircled, World on Edge
China just launched its largest war games around Taiwan to date, sending a clear message: Beijing can cut off the island from the outside world if conflict erupts. The drills, dubbed “Justice Mission 2025,” involved troops, warships, fighter jets, and artillery, with live fire and simulated strikes designed to test Taipei’s defenses and U.S.-made weapons.
“Conducting live-fire exercises around the Taiwan Strait ... would not only constitute military pressure on us, but could also pose more complex challenges and impacts for the international community and neighbouring countries.”
— Hsieh Jih-sheng, Taiwan’s deputy chief of defence
The drills covered a record seven zones, some closer to Taiwan than ever before, and forced the cancellation of hundreds of flights. China’s military released propaganda videos showing futuristic tech—automated robots, microdrones, and weaponised robotic dogs—while Taiwan’s defence ministry responded with its own footage of U.S.-made HIMARS rocket systems.
Analysts say these exercises blur the line between training and actual preparation for invasion, aiming to give the U.S. and allies minimal warning. China’s state media insists the drills are a response to increased U.S.-Taiwan military cooperation, while Taiwan’s government remains on high alert, coordinating rapid-response exercises and deploying ships to face off with Chinese vessels.
So, is this just another show of force—or the opening act of something far more dangerous?
