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.

🇽🇰#Kosovo: Kosovo Police has found yet another cache of weapons, ammunition, and military gear yesterday, after searching the basement of a residential building on Vasilije Ostroški Street in North Mitrovica.
Officers recovered multiple assault rifles, hundreds of rounds of ammunition, magazines, a smoke grenade, body armor, and various pieces of military clothing and equipment. No arrests were made, and an investigation into illegal weapons possession is ongoing.
This comes as, over the past week, several abandoned weapons caches have been discovered in the north, including one containing hundreds of kilograms of explosives and a practice anti-tank mine. It remains unclear whether the stashes are linked to a specific paramilitary group or a criminal organization.

The latest seizure was yesterday in Mitrovicë Veri, where police, acting on information from citizens, found several illegal weapons, ammunition, and a VPMA-2 (a practice version of the PMA-2 anti-personnel mine).
