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

Did you manage to catch these pastel-coloured altocumulus clouds at sunset? When the sun is at a low angle on the horizon, sunlight travels across a longer distance through the atmosphere before reaching our eyes. As a result, blue colours are scattered by atmospheric particles, leaving behind brilliant hues of pink, orange and yellow. 📷: peiqiitohh #SGWeathergrams#WeatherWednesday

If you were in the Newton area on 25 May, you may have spotted this huge woolly blanket in the sky! This blanket of dense clouds was formed as the top of a cumulonimbus cloud collapsed following strong thunderstorms across Singapore earlier that morning. Named “cirrus spissatus”, these rarer upper atmosphere clouds are thicker and denser, and would block out the sun. The Latin word “spissatus” in its name describes its thicker appearance. 📷 Photo by _quietude__ #SGWeathergrams#WeatherWednesday

Hello Halo! Did you spot it this afternoon? These faint coloured rings encircling the sun are formed by the refraction of the light through ice crystals in high-level clouds under relatively clear conditions. #SGWeathergrams#SGWeather

#WeatherWednesday#throwback to the sunrise on 17 Jun, when we were greeted by this beautiful scattering of cirrocumulus stratiformis clouds. The Latin word “stratiformis” means “stretched out”, referring to its irregular, dotted, blanket-like appearance. 📷 Photo by knifematchneedle #SGWeathergrams
