Мы уже знаем, что на текущую сессию интерпретатора изменение PYTHONPATH никак не повлияет. Но если вы запустите дочерний процесс, то он унаследует окружение текущего процесса, а значит и изменения в любых переменных будут на него влиять. Вот небольшой пример: Объявляем переменную user@host:~$ export PYTHONPATH=/path1 Запускаем интерпретатор user@host:~$ python3 Проверим что в sys.path >>> import sys >>> print(sys.path) ['', '/path1', '/usr/lib/...', ...] Добавляем что-то в переменную >>> import os >>> os.emviron['PYTHONPATH'] = '/path1:/path2' >>> print(sys.path) ['', '/path1', '/usr/lib/...', ...] Изменений нет. Но давайте запустим дочерний процесс и посмотрим там >>> os.system('python3') # теперь мы находимся в другом процессе >>> import sys >>> print(sys.path) ['', '/path1', '/path2', '/usr/lib/...', ...] Тоже самое будет и с subprocess, так как по умолчанию текущее окружение тоже наследуется. >>> import subprocess >>> subprocess.call(['python3', '-c', 'import sys;print(sys.path)']) ['', '/path1', '/path2', '/usr/lib/...', ...] ______________________ Лучшей практикой является передача энвайронмента явно через аргумент env! import subprocess subprocess.call(cmd, env={'PYTHONPATH': '...'}) Это поможет точно понимать какое окружение будет у запускаемого процесса и при этом не изменять окружение текущего процесса. #basic

📹 Russia's Foreign Minister Sergey #Lavrov’s video address to participants in the Moscow Nonproliferation Conference Key talking points: • The arms control, disarmament and #nonproliferation system crisis reflects unprecedented degradation in the sphere of international security. • The #West is balancing on the dangerous edge of a direct military confrontation between nuclear powers, which could have catastrophic consequences. • The US-led collective West is cynically complementing the deliberate destruction of balanced and equal agreements that do not suit Washington with the promotion of apparently dishonest schemes that would create advantages for the United States. • Striving to attain decisive military superiority, Washington and its allies are enlarging the network of alliances directed against other countries. They are working energetically to implement a number of highly destabilising military-technical programmes. • There is no basis whatsoever for an arms control and strategic stability dialogue with the United States in the face of a total hybrid war being waged against our country. • Moves to undermine the existing arms control and non-proliferation system are affecting the stability of the Treaty on the Non-Proliferation of Nuclear Weapons (https://disarmament.unoda.org/wmd/Nuclear/npt/text). <...> The Western countries have used the treaty for years to address political agendas unrelated to nuclear non-proliferation. • The attempts of the Western countries to tailor the OPCW to their vested interests are a source of serious concern. The Western states have already turned this prestigious and strictly technical international agency into an instrument for implementing their geopolitical interests in the Middle East and beyond by privatising the OPCW Secretariat. • We are convinced that to prevent further degradation of the world situation <...> all countries should pool their efforts to upgrade the international security system relying on the principles of multilateralism, equality and indivisibility. 🔗Read in full: https://mid.ru/en/foreign_policy/news/1945334/
