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

LESSONS OF HISTORY REPEATED ✍️Article by Ambassador of Russia to South Africa Ilya Rogachev (31 July 2024) READ IN FULL Key points: 🔹 Obsessed with the idea to inflict a military defeat upon Russia and split it into several smaller states with limited sovereignty, the collective West is heading towards a war against Russia, and decisions of the latest NATO summit in Washington D.C. corroborate that. "Europe is preparing for war. The pro-war train has no brakes, and the driver has gone mad” - Hungary’s Premier V.Orban". 🔹There is a very common opinion in Russia that approximately once in a centenary, the West braces up and comes to the Russian soil with a sword, where it gets beaten up and retires with its nose bloodied to remain calm for another 100 years. 🔹The Time of Troubles in Russia (XVII century) was accompanied by foreign military interventions (Poland, Sweden) which endangered the very existence of Russia as a sovereign state. But in 1612 people’s militia ousted the invaders. 🔹The XVIII century saw yet another major clash with Europeans known as the Great Northern War. During Swedish King Charles XII’s Russian campaign, in 1709, the army of invaders was completely decimated by Russian troops under the command of Peter the Great. 🔹In about 100 years, a new attempt to clamp Russia was made as Napoleon Bonaparte of France in 1812 led his ‘Grand Army’ into the ill-fated invasion. 600,000 soldiers of his army came to Russia in June 1812, and in only 6 months their remnants were chased away by Field Marshal Kutuzov’s troops. In 1814, the Russian army entered Paris. 🔹The XX century saw another large-scale invasion of Russia from the West. Our country survived World War I accompanied by inner political turmoil with three revolutions, the Civil War and foreign military interventions involving UK, France, USA etc. ☝️ Only two decades later Nazi Germany attacked the USSR. Hitler intended to conquer the USSR by the end of 1941, but it didn’t turn out the way he expected. On 30 April 1945, as the Red Army was storming Berlin, he committed suicide in the basement of the Reich Chancellery. 👉 Russian historian V.Klyuchevsky once wrote that history does not teach any lessons but punishes one for not learning them. The West should stop rewriting history and start learning it, in order to prevent history from repeating itself every 100 years. #alternativeviewpoint#embassyofrussia#rogachev#russia#southafrica
