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()

The father stands there. The daughter, who starts off playfully laughing.... is shocked to see her father standing there despite her progress.
When the father steps forward for the final question, she hugs him. Father - Daughter ❤️
Children can be raised without knowing hardship.
But it is important to make them know that nothing they get comes so easily ❤️
