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.

🇺🇸US soldier arrested for betting on Maduro’s capture — won over $400 000💰
A U.S. Army Special Forces master sergeant, Gannon Ken Van Dyke, has been arrested and charged after allegedly using classified military information to place bets on an online prediction market and win more than $400 000 based on the outcome of a covert operation that captured Venezuelan president Nicolás Maduro.
Van Dyke, who was involved in Operation Absolute Resolve — the U.S. military mission that led to Maduro’s capture on January 3 — reportedly placed about 13 bets on the platform Polymarket, wagering that Maduro would be removed from power. Prosecutors say he used nonpublic knowledge of the operation to make strategic trades that paid off once the raid became public.
Federal authorities have indicted him on multiple counts, including unlawful use of confidential information for personal gain, commodities fraud, wire fraud, and illegal use of classified data. Van Dyke allegedly tried to conceal his identity and the proceeds by using foreign cryptocurrency accounts and requesting deletion of his Polymarket account after the operation was announced.
Officials and lawmakers have condemned the case as a serious breach of trust and a form of insider trading in prediction markets, highlighting concerns about the misuse of secret information for profit.
