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

I rushed down stairs. The wild energy around her was affecting me. Not only affecting me but turning me into the perfect dumbass. So I thought its good idea if I catch up with my buddy before a vapourising. Reaching on the last step, I looked up at the direction of my room. One second... What she is doing in my room? Rubbing the temple of my head, I dismiss all the cascading thoughts and marched towards the kitchen. "Oww, Holy hell" One second I was marching with my head held high and now I was embracing the pavement. Wow just great. I haven't been this lucky in my whole life. And suddenly I was showered with the God's grace. And I don't think I like it. "Sir...what are you doing on the floor" A very confused Lola, inquired with the bucket that she just emptied on me "I'm kissing the floor, Lola" I replied politely, well my system is shaken now, especially the one which is responsible for my emotions and feelings. "How did you fell ?" Vivek asked in very concerned voice, rushing to me. "No Vivek sir he is not fallen, he is just kissing the floor" Lola beamed from somewhere and I didn't even had energy to facepalm. " And why you are wet?" He inquired " Ohh wow he talks " My lips formed in knowing smile, well it's more like a grin. Actually I was just taunting him. for turning my life upside down. A if it wasn't already. "Yeah sir he talks very much and politely" She beamed again from somewhere and I couldn't do anything more than sighing "Why you are wet? " Vivek asked again ignoring Lola. He is really good in ignoring people. "It's God's grace in liquid form" I murmured, sinking my body in floor. "No sir I just dropped water on him that I was using for cleaning" Stupid woman chirped again, it's better if she murders herself because I will do it brutally and she won't like it, I don't even need to say how ruthless I'm, That idiot doesn't know when to use her mouth and mind, but I'm not even sure if she has mind. #Vivektavinita#Review#paragraph#novel
