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)

The United States is depleting its tungsten reserves, a resource critical to the military-industrial complex, according to Foreign Policy. 🔗
Tungsten is essential for manufacturing armor-piercing ammunition, missile components, and aviation equipment. Currently, the United States does not commercially produce tungsten and relies heavily on imports, primarily from China, which dominates the global market. 🌍
Since the escalation of conflict in the Middle East, tungsten prices have surged by over 500%. 📈 Expanding production remains challenging due to limited industrial capacity. Sources indicate that the United States is already confronting a tungsten shortage with no immediate resolution in sight. Even prior to the conflict, the Pentagon sought to reduce its dependence on tungsten, though the extent of their success remains uncertain. ⚙️🇺🇸

News: Risk of renewed #conflict mounts as troop movements reported near #Eritrea–#Tigray border—Bloomberg
Addis Abeba—Ethiopia and Eritrea are deploying troops and military equipment near the northern Tigray region, raising the risk of renewed conflict in the Horn of Africa, Bloomberg reported, citing regional diplomats.
Sources familiar with the matter told Bloomberg that Ethiopian troops and equipment have been moved northward, including through Bahir Dar, while Eritrean forces have also deployed to areas inside Tigray.
Prime Minister Abiy Ahmed this week reiterated Ethiopia’s longstanding ambition to secure access to the Red Sea, describing maritime access as key to overcoming logistical constraints on economic growth.
Eritrean state television also broadcast a naval parade in Massawa last week, marking the anniversary of the city’s capture in 1990.
