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 🤓 #libs#regex

🌎 In the Namib Desert, the welwitschia plant survives for centuries with just two leaves that grow continuously, curling and splitting but never falling off—a marvel of resilience in extreme heat. ✨ #botany⚡#deserts⚡#adaptation 👉subscribe Interesting Planet

🌍 Desert varnish is a thin, dark coating that forms on rocks in arid landscapes over thousands of years. It’s made from wind-blown clay and minerals, creating natural stone “paintings.” ✨ #deserts⚡#aridlandscapes⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography 👉more Channels

In Death Valley’s Racetrack Playa, large rocks, some weighing hundreds of kilograms, move across the dry lake bed, leaving long tracks behind. This happens when a rare set of conditions align. First, rain fills the lake bed with a shallow layer of water. At night, the water freezes into thin sheets of ice. As the sun warms the ground, the ice breaks into large, floating panels. Light winds then push the ice, slowly moving the rocks across the playa. The tracks left behind can last for decades, creating unique patterns. This natural process has been understood by scientists and is one of the most fascinating geological phenomena. 🪨❄️🌞 [Read more] @googlefactss #Nature#WeirdFacts#Geography#DidYouKnow#Deserts#Science#Mystery
