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.

News: Overloaded Isuzu truck carrying dozens atop grain overturns, leaving at least 19 dead in #Amhara region
The accident shows the persistent risks associated with the widespread use of cargo trucks for passenger transport in rural Ethiopia, where limited transport options, now exacerbated by chronic fuel shortages across the country, often force residents to travel under dangerous conditions.
Many of the victims were residents of the same locality, often traveling together in groups for work between Tsagibji and Ebnat localities. “Yesterday [Sunday] alone, we sent 17 bodies back to one specific area,” the official said, adding that several victims were members of the same families.
The Deputy Commander also said the area where the accident occurred has been under the control of Fano fighters for the past three years, preventing authorities from reaching the scene to investigate the cause of the crash.

#Ethiopia: Federal Police say its forces "seize illegal weapons" intended for "terrorist purposes" after arriving in #Addis_Abeba from #Amhara region
Addis Abeba: The Ethiopian Federal Police claimed its forces have “seized illegal weapons”, “intended for terrorist purposes” after the arms allegedly arrived in Addis Abeba “from the Amhara region.”
In a statement, the Federal Police said the first seizure occurred at the Legetafo checkpoint, where officers “intercepted a vehicle”.
Following what the federal police claimed as a “rigorous inspection,” authorities discovered “eight AK-47 assault rifles, 151 rounds of AK-47 ammunition, 17 rounds of Bren machine gun ammunition, and seven AK-47 magazines concealed inside the vehicle.”
“The illegal weapons were being transported for terrorist purposes,” the Federal Police said, adding that the suspects were “detained at the scene.”
