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)

Welcome, New Space Cadets! 💫
Since Monday, we've welcomed an incredible 600k new space cadetsto our mission! 🚀 With so many explorers joining, here's a quick reminder about the journey ahead.
Your ship and crew are built for one epic trip only. After each successful mission to the moon, you level up and need to construct a brand new spaceship🚀 and recruit a fresh crew to set off on your next journey.
🌌New Ship: Each mission gives you the opportunity to build even cooler, more powerful ships. Your level increases with every successful expedition, unlocking better designs and greater mining power.
🌌Fresh Crew: Invite new friends to join your adventures. Each new expedition requires a full crew, and more friends mean greater strength and success. No friends? No prob! Use special bots.
🌌Continuous Exploration: The adventure never ends! Keep exploring the cosmos, completing missions, and reaping stellar rewards.
🌌Balance Intact: Levelling up doesn’t reset your Space Bucks balance. You keep all your hard-earned Space Bucks as you progress.
ℹ️ For more info, check the mission manual here.
Every journey helps you level up, bringing you closer to mastering the cosmos. So gear up, build your fleet, and keep pushing the boundaries of space exploration: the end of season 1 & the first token airdrop are coming!🔔
