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

October 11, 2021: Alaska quake, U.S. and Taliban, AstraZeneca, Prince Andrew, California oil spill October 11, 2021: Alaska quake, U.S. and Taliban, AstraZeneca, Prince Andrew, California oil spill 1. An earthquake of magnitude 6.8 struck the Alaska Peninsula region, the European Mediterranean Seismological Centre said. 2. The United States said on Sunday the first face-to-face meeting between senior U.S. and Taliban officials since the hardline group retook power in Afghanistan was "candid and professional" and that the U.S. side reiterated that the Taliban would be judged on their actions, not just their words. 3. AstraZeneca's experimental COVID-19 drug has helped cut the risk of severe disease or death in a late-stage study, the British drug maker said, a boost to its efforts to develop coronavirus medicines beyond vaccines. 4. British police said they would be taking no further action after conducting a review of evidence relating to sex crime allegations against Queen Elizabeth's son, Prince Andrew, and the late U.S. financier Jeffrey Epstein. 5. Beaches in a southern California city that were shut because of an oil spill last week are set to reopen, authorities said in a statement. #Alaska #Earthquake #UnitedStates #Taliban #Afghanistan #AstraZeneca #Covid19 #UnitedKingdom #BritishPolice #PrinceAndrew #Epstein #QueenElizabeth #Headlines #MorningNews #Business #News #Reuters Subscribe: http://smarturl.it/reuterssubscribe Reuters brings you the latest business, finance and breaking news video from around the globe.
