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 just 2 days, the Centre for Liveable Cities (CLC) and the Urban Redevelopment Authority (URA) will jointly organise our flagship event of the year – World Cities Summit (WCS) 2022! The Summit will return to an in-person conference format this year, and will convene government and industry leaders, and leading experts from around the world to address liveable and sustainable city challenges, share integrated urban solutions and forge new partnerships. Over the course of 4 days, WCS delegates will engage with this year’s theme - “Liveable and Sustainable Cities: Emerging Stronger” – through a series of discussions on how cities need to remain liveable, sustainable, and more resilient, in these times of prolonged and unpredictable disruptions, such as pandemics and climate change!
