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

Question ppl ask me often How can I improve my writing skills? Here is my reply Improving your writing skills is a valuable endeavor that can benefit you in many areas of life. Here are several strategies you can use to become a better writer: 1. Read Regularly: - Diverse Materials: Read a variety of genres, including fiction, non-fiction, journalism, and academic papers. This exposes you to different styles and vocabularies. - Analyzing: Pay attention to how authors construct sentences, develop ideas, and build arguments. Reflect on what makes their writing effective or ineffective. 2. Write Daily: - Journaling: Keep a daily journal to practice writing regularly. It doesn’t have to be formal; the goal is to make writing a habit. - Prompts: Use writing prompts to challenge yourself and spark creativity. Websites and books often offer daily prompts. 3. Learn the Basics: - Grammar and Syntax: Brush up on grammar and syntax rules. Resources like "The Elements of Style" by Strunk and White can be very useful. - Vocabulary: Expand your vocabulary through reading and using tools like a thesaurus. 4. Seek Feedback: - Peer Review: Share your writing with friends, colleagues, or writing groups to get constructive feedback. - Professional Feedback: Consider hiring a writing coach or taking a writing course. 5. Revise and Edit: - Multiple Drafts: Don’t be afraid to write multiple drafts. Revision is a crucial part of the writing process. - Editing: Learn to edit your work critically. Look for clarity, coherence, conciseness, and correctness. 6. Study Writing Techniques: - Workshops and Courses: Enroll in writing workshops or online courses. Websites like Coursera, Udemy, and edX offer courses on various aspects of writing. - Books on Writing: Read books about writing, such as "On Writing" by Stephen King or "Bird by Bird" by Anne Lamott. 7. Practice Different Styles: - Genres: Experiment with different genres (e.g., poetry, essays, short stories, technical writing) to find your strengths and preferences. - Perspectives: Write from different perspectives and in various voices to develop versatility. 8. Use Writing Tools: - Software: Use tools like Grammarly, Hemingway Editor, or ProWritingAid to help with grammar and style. - Outlining: Use outlining tools to organize your thoughts before you start writing. 9. Stay Motivated: - Set Goals: Set specific, achievable writing goals (e.g., write 500 words a day, complete a short story in a month). - Celebrate Progress: Acknowledge and celebrate your progress to stay motivated. 10. Read Aloud: - Hearing Your Writing: Reading your work aloud can help you catch errors and awkward phrasing that you might miss when reading silently. Improving your writing skills is a continuous process, and persistence is key. By integrating these strategies into your routine, you'll gradually become a more confident and effective writer. #sirjimmy#teamjimmy#writingskills#englishmadeeasy#truewisdom
