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().

During out talks with F-Droid users at FOSDEM26 we were baffled to learn most were relieved that #Google has canceled their plans to lock-down #Android.
Why baffled? Because no such thing actually happened, the plans announced last August are still scheduled to take place. We see a battle of PR campaigns and whomever has the last post out remains in the media memory as the truth, and having journalists just copy/paste Google posts serves no one.
But Google said… Said what? That there’s a magical “advanced flow”? Did you see it? Did anyone experience it? When is it scheduled to be released? Was it part of Android 16 QPR2 in December? Of 16 QPR3 Beta 2.1 last week? Of Android 17 Beta 1? No? That’s the issue… As time marches on people were left with the impression that everything was done, fixed, Google “wasn’t evil” after all, this time, yay!
While we all have bad memories of “banners” as the dreaded ad delivery medium of the Internet, after FOSDEM we decided that we have to raise the issue back and have everyone, who cares about Android as an open platform, informed that we are running out of time until Google becomes the gate-keeper of all users devices.
Hence, the website and starting today our clients, with the updates of F-Droid and F-Droid Basic, feature a banner that reminds everyone how little time we have and how to voice their concerns to whatever local authority is able to understand the dangers of this path Android is led to.
We are not alone in our fight, IzzyOnDroid added a banner too, more #FDroid clients will add the warning banner soon and other app downloaders, like Obtainium, already have an in-app warning dialogue.

Super Bowl Ad TRICKING You Into Welcoming Surveillance State!
During the Super Bowl, you may have seen a commercial for #Amazon’s #Ring “Search Party” feature, which uses an emotional lost-dog story to encourage adoption of participation in what amounts to a widespread neighborhood #surveillance net. Jimmy points out that the ad masks #privacy risks tied to AI-driven #cameras, data sharing, and Amazon’s broader surveillance ecosystem, including concerns about opt-out defaults and government access.
He and Americans’ Comedian Kurt Metzger expand the discussion into a broader critique of social media and smart devices as tools of self-surveillance, suggesting public safety and convenience are being used to justify constant monitoring. Ultimately, it frames the commercial as emblematic of a growing surveillance state presented as benevolent technology.
