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.

The sunrays taking;
All the darkness away,
Love taking all hatred away,
Miniature hopes in shapes of stars,
Now subsiding in beautiful destiny,
Happiness taking all the pain away.
In midst the beautiful world,
I laid here,
Breathless,
My sould taken away by you,
My heart given to beat in someones
Else's cage,
My body drifted with fire,
My voice taken away by deafening silence,
My memories now, washed away,
Fading away with new ones.
This is how,
A beautiful day began,
Changing my life,
To be dreadful forever,
In midst the beautiful world,
I laid here as a dead lover.

She's like a poem,
Waiting to be read.
She's like a song,
Waiting to be sung.
She's like a melody,
Waiting to be heard.
She's like a book,
Waiting to be understood.
She's like a dance,
Waiting to be performed.
She's like a beauty,
Waiting to be cherished.
She's like art,
Waiting to be crafted.
She's you,
Waiting to be found.
She's you,
Waiting to be loved.
She's not just a girl,
She's within all of you,
She resides somewhere inside,
Somewhere the golden rays don't reach,
Somewhere the silver shine doesn't work,
Somewhere in you,
She stays,
Waiting to be acknowledged.

During a dreadful night,
I managed to put up a fight.
Maybe the strong me died,
And weak me survived.
The constant voices in my ears,
Here I am living in my fears.
Like a painful reminder of that night,
Where I lost a outnumbered fight.
Wondering if I am even right,
While holding myself tight.
The night is long dead,
Here my tears still wetting my bed.
That dreadful night,
The cause of my fright.
These thoughts make me shiver,
The fear making me quiver.
My painful screams,
Still haunting my dreams.
Maybe the strong in me died,
And weak me survived.
I haven't given up the fight,
Because I know,
I can still make it right.
