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

🪐 Spanning more than 300 light-years, a vast radio structure known as the "Orion Spur Radio Arc" weaves through our segment of the Milky Way. Detected by the LOFAR radio telescope, this arc is composed of incredibly energetic electrons spiraling around magnetic fields, revealing a hidden backbone of cosmic magnetism threading through our stellar neighborhood. ✨ #MilkyWay⚡#magnetism⚡#radio 👉subscribe Universe Mysteries

🌎 The mysterious Whistler waves are very low-frequency radio signals generated by lightning. They travel along Earth's magnetic field lines and can be converted to eerie whooshing or whistling sounds when played back as audio. These signals were first recorded by radio operators during World War I. ✨ #lightning⚡#magnetism⚡#radio 👉subscribe Interesting Planet

🪐 In the constellation Lynx lives an unusual star known as HD 45166, which has an incredibly strong magnetic field—about 43,000 times greater than Earth’s. This rare "magnetized helium star" shrouds itself in a thick, fast-moving wind of gas, and its unique magnetic properties provide astronomers with a rare look at how intense magnetism can shape the life and appearance of stars. ✨ #unusualstars⚡#magnetism⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In the constellation Monoceros, the star HD 45166 is an unusually magnetic massive star with a surface magnetic field nearly 43,000 times stronger than Earth's. This extreme magnetism shapes the flow of gas around the star, producing powerful outflows and making HD 45166 a rare laboratory for studying the effects of magnetism on stellar evolution. ✨ #stars⚡#magnetism⚡#Monoceros⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
