Как разделить строку с shell-командой на отдельные аргументы в виде списка?
Если сделать просто сплит по пробелу то получим то что надо, кроме случаев со вставками текста с пробелами. Например так:
>>> '-arg "I Am Groot"'.split(' ')
['-arg', '"I', 'Am', 'Groot"']
Чтобы учитывать текст в кавычках как единый аргумент можно воспользоваться функцией shlex.split()
Кто читает мой канал давно, уже в курсе.
А что делать, если нужно обратное действие? Объединить аргументы из списка в строку и при этом добавить кавычки в аргумент с пробелами.
Конечно, если вы используете subprocess то он сам всё разрулит. Но если вам нужна именно команда одной строкой, то можно воспользоваться готовой функцией в том же subprocess.
>>> from subprocess import list2cmdline
>>> list2cmdline(['-arg', 'I Am Groot'])
'-arg "I Am Groot"'
Он также позаботится об экранировании уже имеющихся кавычек
>>> list2cmdline(['-arg', 'I Am "Groot"'])
'-arg "I Am \"Groot\""'
А вот так он может "схлопнуть" в команду JSON
>>> list2cmdline(['--json', json.dumps({'key': 'value'})])
'--json "{\"key\": \"value\"}"'

Возможно кто-то спросит, а зачем соединять аргументы в строку если subprocess сам это сделает а os.system не наш путь?
Мне как-то потребовалось отправлять команду на удалённое выполнение и в API поддерживалось указание команды только строкой. Так что всякое бывает)
