Регулярно требуется преобразовать какой-либо текст в максимально совместимый текст для URL, имени файла, имени объекта в каком-то софте и тд. Требования совместимости простые: в тексте должны быть только допустимые символы. Обычно это a-z, 0-9 и "_" или "-". То есть, только прописные буквы латинского алфавита и цифры (как пример). Допустим, нам нужно название статьи в блоге преобразовать в slug для добавления его в URL этой статьи. Как это лучше всего сделать? В Django по умолчанию есть готовая функция slugify для таких случаев. Но я её никогда не использую. Почему? Потому что её недостаточно! Приведём пример >>> from django.utils.text import slugify >>> slugify('This is a Title') 'this-is-a-title' Пока всё отлично >>> slugify('This is a "Title!"') 'this-is-a-title' Спец символы удалились, всё хорошо. >>> slugify('Это заголовок статьи') '' Вот и приехали 😢. Если текст не английский то буквы просто игнорируются. Можно это поправить >>> slugify('Это заголовок статьи', allow_unicode=True) 'это-заголовок-статьи' Но тогда мы не вписываемся в условие. У нас появилась кириллица в тексте. Так как я часто пишу сайты для русскоязычных пользователей эта проблема весьма актуальна. Я не использую стандартную функцию и всегда пишу свою. Оригинал я не беру в расчёт и пишу полностью свою функцию. И так, по порядку: 🔸1. Исходный текст: >>> text = 'Мой заголовок №10 😁!' Взял специально посложней со специальными символами. 🔸2. Транслит Необходимо сделать транслит всех символов в латиницу. Здесь очень выручает библиотека unidecode. Помимо простого транслита кириллицы в латиницу она умеет преобразовывать спец символы и иероглифы в текстовые аналоги. from unidecode import unidecode >>> unidecode("Ñ Σ ® µ ¶ ¼ 月 山") 'N S (r) u P 1/4 Yue Shan' Очень крутая библиотека, советую👍 В нашем случае получаем такое преобразование: >>> text = unidecode(text) >>> print(text) 'Moi zagolovok No. 10 !' Отличный транслит. Смайл просто удалился, хотя я ждал что-то вроде :). Ну и ладно, всë равно невалидные символы. А еще наш код уже поддерживает любой язык, будь то хинди или корейский. 🔸4. Фильтр символов Unidecode не занимается фильтрацией по недопустимым символам. Это мы делаем в следующем шаге через regex. Просто заменим все символы на "_" если они вне указанного диапазона. >>> text = re.sub(r'[^a-zA-Z0-9]+', '_', text) >>> print(text) 'Moi_zagolovok_No_10_' Символ "+" в паттерне выручает когда несколько недопустимых символов идут рядом. Все они заменяются на один символ "_". 🔸5. Slugify Осталось удалить лишние символы по краям и сделать нижний регистр >>> text = text.strip('_').lower() >>> print(text) 'moi_zagolovok_no_10' Получаем отличный slug! 😎 🌎 Полный код в виде функции. ______________ PS. Проверку что в строке остался хоть один допустимый символ я бы вынес в отдельную функцию. #libs#tricks#django

*FRACTION OF SECONDS* Woke up. I knew I was late. Coz that was my routine. And coz of a simple logic, why be excited to wake up early and go to a place you hate and do something that you hate! I sighed when my mouth tasted coffee before colgate...Ahh! how I love normal days, It was a normal day. At least that's what I thought. Papa was there looking up from the newspaper at me with a sense of pity. I sort of ignored that and walked out through the front door, but the next sight, a brand new beautiful ladybird and an even more beautiful rider, with short black hair waving in the wind, in a skirt that knew well not to cover her beautiful legs... Well I couldn't ignore that! Just a fraction of seconds and I had already captured her. Made her mine. Is this what they call... Oops!! She looked at me. Damn it! She caught me staring at her! I looked away whistling. I looked again, did I see a smile? I heard Mom shouting my name out aloud. I knew I had to rush. As I was rushing inside I heard a loud thud. I turned back and saw the beautiful ladybird lying on the road. It was only a fraction of second, yet my mind talked to me in infinite speed...Somethings...what did he say I don't remember anymore. I remember rushing back to the house. One year I didn't talk to our new neighbour who was an year older than me.Days went by. Mom had started packing things up one evening I came back from school. Papa received his transfer letter. Now whenever I see a cycle I think. What would've happened? Why hadn't I stopped my mind talking to me? Why hadn't I I rushed 'out'side than 'in'side? All in a fraction of second! #JOHN PAUL BENOY #Review

Former US National Security Advisor John Bolton: “Although you could potentially remove the ayatollah, that would leave the IRGC in place, and the government in Iran is the IRGC, while the ayatollahs act as a religious cover or an ideological cover for them. I think Trump is just hoping that this show of American power will intimidate the ayatollahs. If I were still his adviser, I would be happy to tell him that it won’t work. They won’t be intimidated. But Trump really thinks minute by minute; he doesn’t think strategically.” #john#bolton#trump#ayatollah 📱American Оbserver - Stay up to date on all important events 🇺🇸
