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()

Logitech MX Master 3S — zamonaviy texnologiya va ergonomikaning uyg‘unlashgan cho‘qqisi bo‘lib, RTINGS sinovlarida universal eng yaxshi sichqoncha sifatida e’tirof etilgan.
Uning o‘ziga xos ergonomik dizayni, gorizontal va vertikal g‘ildiraklari hamda gesture-tugmalari bir necha funksiyalarni bir harakat bilan boshqarish imkonini beradi.
4K ekranlar uchun yuqori aniqlikdagi sensor moslashuvi bilan jihozlangani esa bu sichqonni professionallar uchun ayni muddao qiladi.
Bu reklama emas, shunchaki sichqonchani yaxshisini tavsiya qilyapman, o'yin uchun esa Razer Viper V3 Pro eng zo'ri.
Siz qanaqa markadagi sichqoncha ishlatasiz?
