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()
