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

Every day people from all parts of the world would remind me how amazing their lives are and how mine isn't. I notice most of the people around me are just pretending to be happy, they show me what they want me to see not what i'm needed to see. I somehow know the truth but it's just so tough to believe it. It's just that my heart is so used to being sad about every other single situation, now it finds it challenging to become something it has never been. Honestly, my heart gave up on me a long time ago because my dumbass would always try to find reasons to make myself feel like shit. With time I reached a point where I no more cared if I was happy or not.I had no idea about what I was trying to do with myself. I didn't care if I watched that tv show which I used to enjoy, I didn't care if I ate those chicken rolls that my mom prepared just for me because I would beg her to make them, I didn't care if I was healthy, I didn't care about my looks, desires, likes, dislikes. I reached a point where I had no more fucks left with me to give to the world or to myself. During one of the summer holidays my best friend who came to visit me after two whole years would scan my whole appearance with a concerned disgust in his eyes. "Well, you look like shit. I heard from your mom that you haven't eaten anything since last two days. Are you trying to kill yourself or some shit? " I smiled because I finally figured out what I was trying to do with myself.
