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

Who is a real #Muslim? People who are independent. They are not affiliated with the United States. Their leaders are not chosen by the #Illuminati. If a Muslim is attacked in another country, they will help them. Economic embargo and war cannot weaken their faith. They live in Yemen and will carry out a great responsibility in the events of the apocalypse. https://t.me/YediotNewsChat

In the Palestinian war with the Jewish terrorists, the people of the world changed their attitude. The people of the world used to receive news from official media and government-affiliated organizations. News agencies such as Associated Press, France Press, United Press, Reuters and many major news agencies in the world are in the hands of #Zionists. But in the Palestine war, the people of the world turned to individual media such as Telegram, Twitter and Tik Tok to discover the truth. The social networks that were built for the #Illuminati to dominate have become the nightmare of the #Freemasons. https://t.me/YediotNewsChat

The #Jewish media empire portrays Iranophobia in the world. This tourist was told that Iran is a dangerous country, but upon entering Iran, he was surprised by the Zionists' false propaganda against Iran. Imperialists and #Freemasons do not want the people of the world to know Iranian civilization. Because Iranian culture wants to destroy the #Illuminati. https://t.me/YediotNewsChat

Some news sources say that the price of internet has increased in some Muslim countries. Social networks and individual media have become an important tool to deal with the #Zionists. Because the state media is under the control of the #Jews. Official and government news agencies publish selected news in favor of the Zionists. But social networks publish real news. Individual media are putting pressure on Israel. They have increased the price of the Internet to reduce the activity of individual media. Every word and picture published against the Zionists will hit the body of #Illuminati and #Freemasonry like a bullet. https://t.me/YediotNewsChat
