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)

🇺🇸US soldier arrested for betting on Maduro’s capture — won over $400 000💰
A U.S. Army Special Forces master sergeant, Gannon Ken Van Dyke, has been arrested and charged after allegedly using classified military information to place bets on an online prediction market and win more than $400 000 based on the outcome of a covert operation that captured Venezuelan president Nicolás Maduro.
Van Dyke, who was involved in Operation Absolute Resolve — the U.S. military mission that led to Maduro’s capture on January 3 — reportedly placed about 13 bets on the platform Polymarket, wagering that Maduro would be removed from power. Prosecutors say he used nonpublic knowledge of the operation to make strategic trades that paid off once the raid became public.
Federal authorities have indicted him on multiple counts, including unlawful use of confidential information for personal gain, commodities fraud, wire fraud, and illegal use of classified data. Van Dyke allegedly tried to conceal his identity and the proceeds by using foreign cryptocurrency accounts and requesting deletion of his Polymarket account after the operation was announced.
Officials and lawmakers have condemned the case as a serious breach of trust and a form of insider trading in prediction markets, highlighting concerns about the misuse of secret information for profit.
