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

🌎 The invention of the safety elevator by Elisha Otis in 1852 made skyscrapers possible. His design featured a locking mechanism that stopped the elevator if the hoisting cable snapped. Otis demonstrated this life-saving device at the 1854 World’s Fair in New York, boosting public trust in elevators. ✨ #inventions⚡#history⚡#engineering 👉subscribe Interesting Planet 👉more Channels

🌎 X-rays were discovered accidentally in 1895 by German physicist Wilhelm Röntgen. While experimenting with cathode rays, he noticed an unknown radiation that could pass through solids and reveal images of bones. Today, X-rays are a key tool in medicine and industry worldwide. ✨ #inventions⚡#history⚡#physics 👉subscribe Interesting Planet 👉more Channels

🌎 The invention of the modern stethoscope in 1816 by French physician René Laennec transformed medical diagnosis. By rolling paper into a tube, Laennec could hear internal chest sounds clearly, improving detection of lung and heart conditions. The first stethoscopes were made of wood and about 25 centimeters long. ✨ #history⚡#medicine⚡#inventions 👉subscribe Interesting Planet 👉more Channels

🌎 In 1867, Swedish chemist Alfred Nobel invented dynamite by stabilizing volatile nitroglycerin with an absorbent clay called kieselguhr. This made blasting much safer for construction and mining. Nobel later used his dynamite fortune to establish the Nobel Prizes in 1895. ✨ #inventions⚡#chemistry⚡#history 👉subscribe Interesting Planet 👉more Channels

🌎 The accidental invention of safety glass happened in 1903, when French chemist Édouard Bénédictus dropped a glass flask coated with plastic cellulose nitrate. Rather than shattering, the glass cracked but held together, inspiring shatter-resistant windshields. By 1927, safety glass became standard in automobile manufacturing. ✨ #inventions⚡#chemistry⚡#history 👉subscribe Interesting Planet 👉more Channels

The first vending machine was invented in the 1st century AD by Greek engineer Heron of Alexandria. It dispensed holy water when a coin was inserted—the weight tilted a lever, opening a valve to release water before the coin dropped. 💧⚖️ [Learn more] @googlefactss #History#Inventions#Engineering#AncientGreece

🌎 The discovery of radioactivity in 1896 by Henri Becquerel revealed that uranium salts emit invisible energy. This led to the identification of new elements like polonium and radium by Marie and Pierre Curie. Their work contributed to the development of X-ray machines and atomic science. The Curies isolated just 1 gram of radium from 8 tons of ore. ✨ #radioactivity⚡#discovery⚡#inventions 👉subscribe Interesting Planet

🌀💦 South African Invention That Changed Pool Life Did you know the automatic pool cleaner was invented in 🇿🇦 South Africa? 👨🔧 In 1974, hydraulics engineer Ferdinand Chauvier (pictured), who had moved from the Belgian Congo to South Africa, came up with a way to take the hassle out of pool cleaning. The result? The legendary Kreepy Krauly — one of the very first automatic pool cleaners, designed and built in Springs, South Africa. 🌍✨ His invention made pools around the world easier to maintain — and became a proudly South African contribution to everyday comfort. 🏊♂️ From Johannesburg to Los Angeles, millions of pools have been cleaned thanks to Chauvier’s idea. #Inventions#SouthAfrica#Innovation#KreepyKrauly#History#MadeInSA
