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

🌎 Leafcutter ants and certain fungi share a remarkable partnership. Ants bring leaves underground—not to eat, but to feed a specific fungus they cultivate as food. This mutualism has existed for over 50 million years, making it one of the oldest known examples of symbiosis in the animal world. ✨ #symbiosis⚡#ants⚡#evolution 👉subscribe Interesting Planet ​

🌎 Leafcutter ants farm fungus by cutting leaves and bringing them to underground nests. The ants feed the fungus, then eat the fungus as their main food source. Over 47 species of leafcutter ants are found in Central and South America. ✨ #symbiosis⚡#ants⚡#nature 👉subscribe Interesting Planet 👉more Channels ​

🌎 Army ants in Central and South America show remarkable cooperation by forming living bridges with their bodies. These bridges help the colony cross gaps during raids. Colonies can contain over 200,000 worker ants acting as a single super-organism. ✨ #ants⚡#cooperation⚡#symbiosis 👉subscribe Interesting Planet 👉more Channels ​

Ants don't have lungs. They breathe through tiny holes along the sides of their bodies called spiracles. These connect to a network of tubes (tracheae) that deliver oxygen directly to their tissues. [Read more] @googlefactss #Ants#Biology#Entomology#ScienceFacts

🌎 The leafcutter ant creates underground gardens by carrying fresh leaves to feed a special fungus, which is their true food. This farming partnership has evolved over millions of years, making these ants nature’s original farmers long before humans. ✨ #ants⚡#fungus⚡#agriculture 👉subscribe Interesting Planet
