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

I had a big fight with my wife, I yelled at her, "When you finally die, I'm getting you a headstone that says, 'Here Lies My Wife - Cold As Ever'." "Yeah well," she shouted back, "When you die, I'm getting you a headstone that says, 'Here Lies My Husband - Stiff At Last." #roast@Sickipedia

My coworker said: “ You should not eat red meat.” I said, “My grandmother lived to be 97.”… She said, “Did she eat red meat?” I said, “No. She minded her own business.” #roast@Sickipedia

A man who owned a sausage factory was showing his arrogant asshole son around his factory. Try as he might to impress his snobbish son, his son would just sneer and look down his nose at everything. They approached the heart of the factory, where the father thought, "This should impress him!" He showed his son a machine and said, "Son, this is the heart of the factory. With this machine here we can put in a pig, and out come sausages." The son, unimpressed, said, "Yes, but do you have a machine where you can put in a sausage and out comes a pig?" The father, "Yes son, we call it your mother." #roast @Sickipedia
