Что-то вы гоните насчет "привычного вида формата 755 и 644". Я вот вообще не понял что это!😳 Действительно, что означают цифры которые мы получили в прошлом посте? Это кодировка, заключающая в себе режимы доступа к файлу. Подробней можно почитать в статье про chmod. Там можно увидеть альтернативное обозначение того же самого с помощью символов r w x, что значит чтение, запись, исполнение. Чтобы преобразовать восьмеричное число в такое обозначение в Python есть готовая функция >>> stat.filemode(0o755) '?rwxr-xr-x' Мы видим 3 группы по 3 символа, дающие 3 типа доступа для 3 типов юзеров. А что за знак вопроса в начале? Давайте передадим в эту функцию необрезанное значение от os.stat >>> stat.filemode(os.stat(path).st_mode) 'drwxr-xr-x' Это данные, которые мы безжалостно обрезали в прошлый раз😼 Первый символ обозначает тип объекта. Это может быть файл (-), директория (d) или симлинк (l). Вот простая схема данной кодировки [1][3][3][3] │ │ │ │ │ │ │ └──> Others Permissions │ │ └─────> Group Permissions │ └────────> Owner Permissions └───────────> File Type (разверните экран если вы с телефона) Если вы попробуете получить пермишены для симлинка то получите пермишены для файла >>> path = '.venv/bin/python3' >>> stat.filemode(os.stat(path).st_mode) '-rwxr-xr-x' Чтобы получить свойства именно симлинка, нужно это явно указать >>> stat.filemode(os.stat(path, follow_symlinks=False).st_mode) 'lrwxrwxrwx' #tricks#basic

Ginkgo Biloba - 🧠 herb It's a leaf of the ginkgo tree, which is native to China & one of the oldest plants on the planet, having potential to treat Alzheimer's disease & age-related mental decline. It's believed that it works by thinning the blood & thereby improving oxygen flow to the brain. The brain is a glutton for oxygen, so it's possible that even a slight lack of circulation can affect its performance. Gingko improves both attention & memory, but as a brain booster for people with normal mental abilities, it remains controversial. #foods 🚨Source: @HeathSafetyTps

#foods🐟 下次逛超市,你可以留意下超市里的鲑鱼肉是否和上图一样呈现诱人的红色。野生的鲑鱼通常都食用甲壳类动物(比如虾),而虾壳包含虾青素(Astaxanthin),这会使得鱼肉出现肉红色。 但是——你要知道,饲养的鲑鱼肉本身是灰色的!因为人工饲养的鲑鱼(超市鱼肉的来源)由于成本原因,无法喂食活虾,导致养殖的鲑鱼肉其实和其它的鱼肉一样,是灰色的。但这样的话,(知识储备不足的)消费者不愿意购买相貌平平的正常鲑鱼肉,所以养殖业者被倒逼给鲑鱼喂食色素,促使其肉体呈肉红色。讽刺的是,这种食用色素是鱼饲料中最昂贵的成分,占成本的 20%,但其实毫无必要。
