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().

#Commentary: #Oromia’s New Regulation: Legalizing construction on illegally possessed land, enabling geography-based discrimination
Oromia’s Regulation No. 259/2026 (March 2026) legalizes illegally built properties—yet excludes #Shaggar, #Adama, and #Bishoftu. Hassen Mama Muse argues, "This geographic exclusion creates a two-tiered system, violating constitutional equality."
The law covers construction projects from 2013 to 2026 that meet the criteria but excludes some residents from facing demolition. This contradicts Article 25 of #Ethiopia’s Constitution and treaties like the #ICCPR. The regulation also fails Lon Fuller’s "internal morality of law" and exceeds the Council’s authority under Proclamation No. 242/2021.
According to the author, urgent reforms are needed: include all cities, compensate evictees, and review constitutionality." A fair framework must protect all equally," he emphasizes, "or entrench inequality as reform."

News: EPRP calls for nationwide protest on May 8 amid concerns over electoral conditions
The Ethiopian People’s Revolutionary Party (#EPRP) has called for a nationwide peaceful protest to be held on May 8, 2026, citing what it described as the absence of “enabling conditions” for a credible election in #Ethiopia.
In a statement sent to Addis Standard today, the party said the planned demonstrations will take place in several major cities, including #Addis_Abeba, #Mekelle, #Bahir_Dar, #Gondar, #Hawassa, #Adama, and #Ambo, urging #Ethiopians to join what it described as a peaceful effort to demand political reforms.
The EPRP said it supports the transfer of power through elections but argued that current conditions do not allow for a “free, fair, and credible” vote. It accused the ruling Prosperity Party of attempting to conduct what it termed a “pseudo-election” aimed at extending its hold on power, describing the process as
