В стандартном модуле random есть две очень похожие функции random.randint() random.randrange() Обе возвращают случайное значение из указанного диапазона >>> random.randint(10, 20) 12 >>> random.randrange(10, 20) 17 В чем же отличие? Дело в том что у randrange() есть третий параметр step. randint() действительно возвращает случайное число из указанного диапазона. randrange() на первый взгляд делает тоже самое если передать также два параметра. Но есть указать еще и step то наш диапазон усложняется, то есть в него попадёт не полный ряд значений. Например, я хочу получить случайное значение из диапазона но только чётное число. Тогда достаточно сделать так: >>> randrange(10, 20, 2) 16 Таким образом получается что randint это частный случай randrange без указания параметра step. Еще одно важное отличие в том, что randint() включает в диапазон второе значение а randrange() нет. То есть выражение randrange(10, 20) никогда не вернёт 20, а randint(10, 20) вернёт. #tricks#basic

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

The mesmerising patterns formed by these beautiful stratocumulus clouds, seem to be reminding us to keep a safe distance from each other as we go about our daily activities.

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
