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

In a world that is so busy and craves a lot of attention, I'm just here to remind myself of something that I agree with; “simplicity is the essence of happiness”. A Simple Yet Rewarding Life Life is simple. The wisdom of life consists in the elimination of non-essentials. Fewer possessions = more time to spend enjoying life; because we are not worrying about how to pay for our possessions. Sure it is exciting to buy & bring home lots of stuffs like the latest electronic gadget but after a while, the excitement wears off anyway 🤷🏻‍♀ & here's a reminder in case we forgot; our self-worth is not measured by the material thing we possess. In fact, possessions often end up weighing us down – with them, come responsibility, guilt and stress. For example; your expensive car eats large chunk of your salary from the monthly instalments, insurance, services and road tax as well as the gas and repairment fees (if any)! You must hold on to your job to maintain your car as if you are a slave to it. “The things that we own, end up owning us.” The feeling of guilt comes when you feel that you have overpaid for something or should not have bought it in the first place. For example; tread mill or any other exercise machine 🙍🏻‍♀ Needless to say, stress will come from paying high price for it & worrying about losing them; either by them being broken or stolen. What more is needed to say? Simpler life = doing much with less. 😊 #simplicity#life#minimalism#minimalist#happiness @quietworld🍃
