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
