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().

Appian CEO Challenges AI Industry to Prioritize Trust
Matt Calkins, CEO of Appian, has called on the AI industry to prioritize responsible development and trust. At a critical moment for AI, Calkins unveiled guidelines promoting data transparency, user consent, and respect for intellectual property.
"We must ensure AI flourishes by building trust," Calkins stated. His four principles include disclosing data sources, using private data with consent, anonymizing personally identifiable data, and compensating for copyrighted information. These steps aim to shift AI development from a data race to a trust race.
As AI faces increasing scrutiny, Calkins positions Appian as a leader in responsible AI, encouraging others to join this movement. Trust, he argues, will unlock AI's full potential and redefine industry success.

Market Trends Impact Developer Salaries
Developers face salary stagnation as the job market grows competitive. With more candidates than job openings, mid-senior professionals find job switches yield minimal salary increases. Becoming a tech lead is rare and corporations limit hiring senior candidates. Stability may lie in entrepreneurship or pet projects instead. Consider exploring these options for long-term financial health.
