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

Sudden rain showers are common in Singapore, so if you leave your pails or plant pots where they can collect water, do pay extra attention and drain these containers if they have collected any water. Here’s a checklist for a thorough #MozzieWipeout: https://go.gov.sg/dengue-checklist

Have you emptied out your flower pot plates after watering your plants today? These plates tend to collect water, and can become mosquito breeding habitats if left unattended. Be sure to add emptying out the flower pot plates to your “To-do List” after watering your plants! Here’s a checklist for a thorough #MozzieWipeout: https://go.gov.sg/dengue-checklist

The annual National Dengue Prevention Campaign was launched today, to rally everyone to take urgent action to prevent mosquito breeding and a possible surge in dengue cases, amidst the continued high Aedes aegypti mosquito population, and higher circulation of less common Dengue virus serotypes. The fight against dengue involves all of us. Let’s step up dengue prevention by doing the #MozzieWipeout regularly. go.gov.sg/mozzieproof

Do you know where are the favourite places for mosquitoes to lay their eggs? Pails, flower pot plates/trays and ornamental vases are some of the persistent mosquito breeding habitats in homes. It’s time to search for and destroy these breeding habitats! If you’re not sure how, get started here: https://go.gov.sg/dengue-checklist#MozzieWipeout

The number of weekly dengue cases has declined by more than 50% from its peak this year. However, a 12% increase in the Aedes aegypti mosquito population was detected in the last 3 weeks. So let’s not let our guard down; continue doing the #MozzieWipeout at least once a week and taking protective actions (go.gov.sg/stopdenguenow). You can also get regular alerts on areas with higher Aedes mosquito population and dengue clusters on myENV app (www.nea.gov.sg/myENV) with this step-by-step guide!

Think it’s impossible for mosquito eggs to hatch in your dish tray, mere inches away from your cups and plates? It certainly isn’t. All mosquitoes need is a 20 cent-sized drop of water to breed. Time to do a thorough check in your house! #MozzieWipeouthttps://go.gov.sg/dengue-checklist
