Наверняка вы замечали, что в Python есть удобная функция для получения переменной окружения os.getenv(NAME) И её "сестра" для создания или изменения переменных окружения os.putenv(NAME, VALUE) Но почему-то putenv() не работает как должно. Энвайромент не обновляется! os.putenv('MYVAR', '1') print(os.getenv('MYVAR')) ... и ничего 😴 Почему так? На самом деле энвайромент обновляется, но это значение не добавляется в словарь os.environ. Откройте исходник функции os.getenv(). Это просто шорткат для os.environ.get() В то время как putenv() это built-in С-функция. Словарь os.environ (или точней класс из MutableMapping) создаётся из энвайромента в момент инициализации. Функция putenv() самостоятельно его не изменяет. В тоже время, когда вы создаёте или изменяете ключ в os.environ, автоматически вызывается putenv() в методе __setitem__(). То есть, технически putenv() всё делает верно, но в os.environ это не отражается. Можно проверить так: >>> os.putenv('MYVAR', '123') >>> os.system('python -c "import os;print(os.getenv(\'MYVAR\'))"') 123 Я объявил переменную в текущем процессе и вызвал дочерний процесс, который её унаследовал и получил в составе os.environ. Аналогично при удалении переменной вызывается еще одна built-in функция unsetenv(), удаляющая переменную из системы. Итого ▫️ Удобней всего явно обновлять переменные через os.environ ▫️ Есть способ неявно создать/удалить переменную через putenv/unsetenv, что не повлияет на os.environ но изменит энвайромент и передаст изменения сабпроцессам. Но так лучше не делать! ▫️os.environ это просто обертка для built-in функций putenv() и unsetenv(). #basic

Putin Changes Income Declaration Rules for Officials Vladimir Putin signed a law requiring officials to declare the total family income—covering themselves, their spouses, and minor children—without detailed breakdowns. Pre-marriage spousal incomes are excluded but may appear in expense declarations. The law limits oversight of transactions and assets made before appointment or marriage, excluding them from inspections and penalties. #Russia#Officials#Income#Law The main news of Russia and the world ishere.

E-commerce Conversion Crisis E-commerce stores face a critical challenge with low conversion rates from social media traffic—about half of the general average. Despite this, social networks are a major traffic source, with 64% of users making purchases through them, accounting for a third of online sales. This gap presents significant revenue losses for stores that fail to convert this traffic, highlighting a potential market for platforms aimed at boosting conversions.
