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
