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

Over 5,000 dengue cases were reported in the first quarter of 2024, more than double the 2,360 cases reported in the same period last year. Since the start of 2024, the weekly number of reported dengue cases has remained high, at above 300. There have also been 7 dengue deaths this year. Read on at https://go.gov.sg/dengue-outlook-2024 Dengue risk factors present – high Aedes mosquito population, low population immunity against the Dengue virus – may lead to a surge in dengue cases. Collective responsibility and action are critical. Here’s what you can do to prevent mosquito bites and break dengue transmission: S-A-W (especially if you are diagnosed with or suspected to be infected with dengue) ✔️Spray insecticide in dark corners around the house ✔️Apply insect repellent regularly ✔️Wear long-sleeve tops and long pants Let’s practise these #BLOCK steps at least once a week, to protect ourselves and our families from dengue. B-L-O-C-K ✔️Break up hardened soil ✔️Lift and empty flowerpot plates ✔️Overturn pails and wipe their rims ✔️Change water in vases ✔️Keep roof gutters clear and place BTI insecticide inside 📲Download the myENV app to receive alerts on high Aedes mosquito populations near you, or visit https://go.gov.sg/dengue-high-risk Areas with higher Aedes aegypti mosquito population have a higher risk of dengue and Zika transmission: https://www.nea.gov.sg/dengue-zika/Aedes

#SGDengueUpdate 208 new dengue cases and 51 active dengue clusters were reported in the week ending 21 Oct 2023. #DidYouKnow that individuals infected with dengue are advised to avoid further mosquito bites, to prevent passing on the virus to mosquitoes and other people in the neighbourhood? They can do so by practising S-A-W. To protect ourselves and our families from dengue and Zika, it is critical that we all play our part and do the #BLOCK steps at least once a week. ⚠️ Urgent action from all is critical to prevent a surge in dengue cases at year-end. Areas with higher Aedes aegypti mosquito population have a higher risk of dengue and Zika transmission: www.nea.gov.sg/dengue-zika/Aedes
