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

I appreciate honesty over everything. If you tell me what it is upfront and give me the option to take it or leave it, I respect that. #truth#realtalk@quietworld🍃

older than us, we were 22 when we were having this conversation), and two of my most observant friends talk about the self-conflict each of our coursemates had as they enter 21. & I wouldn't notice the 'pattern' if my friends didn't point out. & suddenly one of my friends started sharing his moment of depression and how he coped with it. & somehow at that moment I felt like my friends actually noticed my changed behaviour and suspected that there's something bothering my mind and they were actually trying to help me out by asking me out, being with me, spending time with me. & I'm glad that they are wise to not help me out by asking me what's wrong because if they ask me what's wrong , I don't even know what is wrong with me and me realizing that there's something off with me and not knowing what it is gonna make me feel so much wrong 😂 and I'm glad they didn't ask me that question. Instead, they just help me out by being there. I'm so grateful and blessed to have friends like them. I was grateful and I am more grateful now, because I just realized that there's actually so much more blessings I had that I haven't notice more in details until now. :') Anyway this is such a long post I didn't even have any idea that it was gonna be this long I wondered if anyone would even read it from beginning till the end, so here's a quick question, did I managed to keep you engaged from the beginning to the end of this post? 😅 #thoughts#afterthoughts#realtalk#poll @quietworld🍃

You do not miss the person; you miss the feelings you experienced with them. If you were to somehow receive similar feelings, you would dismiss & forget that person. #quotes#love#relationship#realtalk @quietworld🍃
