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()

🪐 Deep in the Milky Way, the star J0247-25B is a true cosmic oddball—it’s a rare "pre-helium white dwarf," meaning it’s caught in the act of shedding its outer layers before becoming a typical white dwarf star. This unusual star is much hotter than normal for its size, giving scientists a unique chance to watch stellar evolution unfold before their eyes and providing clues about how stars change shape and temperature toward the end of their lives. ✨

🪐 One of the most unusual stars known is SDSS J122859.93+104032.9, a "carbon-rich white dwarf" about 1,000 light-years from Earth. Unlike typical white dwarfs—stellar remnants made mostly of hydrogen and helium—this star's atmosphere is packed with carbon, giving it a faint, bluish glow and defying expectations about how dying stars shed their outer layers. ✨

🪐 The star HD 49798, located about 2,000 light-years away in the constellation Puppis, is an unusual subdwarf that forms a pair with a mysterious, ultra-dense white dwarf companion. The white dwarf is spinning at a record-breaking speed of just 13 seconds per rotation, making it one of the fastest-spinning white dwarfs ever found and offering a glimpse into rare, exotic outcomes of stellar evolution. ✨
