Как правильно проверить атрибуты доступа файла? То есть доступна ли запись в файл или является ли он исполняемым? Для этого в Python есть функция os.access() Проверять так: os.access(path, flag) Функция вернёт bool в зависимости от наличия указанного флага. Всего есть 4 флага проверки: os.F_OK - наличие файла на диске os.R_OK - доступ на чтение os.W_OK - доступ на запись os.X_OK - доступ на исполнение Например, вместо try-except лучше делать так (пример из документации): if os.access("myfile", os.R_OK): with open("myfile") as fp: return fp.read() #basic#libs

Male and female crabs can be distinguished by looking at their abdominal flap (apron) shape, with males having a narrow, triangular (or T-shaped) apron and females possessing a broad, rounded, or U-shaped apron. Females, often called "sooks," use this wide abdomen to carry eggs, while males ("jimmies") generally have larger claws. @googlefactss#crustaceans

🌎 The yeti crab was discovered in 2005 near deep-sea hydrothermal vents in the South Pacific. Its pincers are covered with hair-like bristles that host bacteria, which the crab farms for food. This crab lives 2,200 meters below the surface, where sunlight never reaches. ✨ #ocean⚡#animals⚡#crustaceans 👉subscribe Interesting Planet 👉more Channels

🌎 Beneath the Ross Ice Shelf in Antarctica, researchers discovered a thriving community of tiny amphipod crustaceans living over 500 meters below the ice. Scientists accessed this hidden ecosystem in 2015 by drilling through the thick ice, revealing life where sunlight never reaches. This shelf covers an area roughly the size of France. ✨ #ocean⚡#Antarctica⚡#crustaceans 👉subscribe Interesting Planet 👉more Channels
