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

🌍 The world's largest freshwater reserves are hidden underground as groundwater, not in lakes or rivers. These reserves are vital for drinking water and irrigation in many regions. ✨ #groundwater⚡#freshwater⚡#resources⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌍 Rainwater can travel deep underground, sometimes moving through rock layers for thousands of years before resurfacing as springs. This hidden journey is a key part of Earth's water cycle. ✨ #hydrology⚡#groundwater⚡#springs⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

🌎 Amsterdam’s famous canal system shaped the city’s landscape but also lowered the local water table. Over 1,500 wooden bridge and building foundations are now monitored for rotting due to changing groundwater levels. ✨ #Amsterdam⚡#canals⚡#urbanization⚡#groundwater 👉subscribe Interesting Planet 👉more Channels
