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)

@RusEmbMalta Press release
On the anniversary of the Declaration of Ukraine’s independence
🔷 On August 24, 2024, Kiev celebrated a state holiday – the #Independence Day of Ukraine.
The Kiev regime keeps trying to boast about its supposed “victories”, successful banderization and forced ukrainianization. It is the geopolitical and mercantile interests of the West that in fact stand behind its “support”
of Ukraine, while this country is assigned the role of a “puppet” and “cannon fodder”.
🔷 The representatives of Zelensky's junta hardly dare to publicly discuss the violation of the provisions adopted in July 1990.
🔷 The heirs of Goebbels do not mention the real losses of the country and the missed opportunities during 33 years of “independence”, total depopulation and loss of whole industries. Kiev got into complete dependence on financial and material submits of the West, for which future generations of Ukrainians will have to pay.

VCs Retreat from Crypto Market
In 2023, analysts noted a significant decline in venture capital investments in cryptocurrency projects, returning to levels reminiscent of 2017. However, some initiatives are aiming to revive the industry’s original spirit of independence from VC influence, at least in principle. Insights provided by Oleg CasCoin for ForkLog. Read more

🚀 AI TRENDS | OpenAI's Sam Altman Addresses AI Development Concerns and Recent Incident
OpenAI founder Sam Altman has expressed understanding of societal fears regarding the rapid development of artificial intelligence. According to Odaily, Altman acknowledged that the current period is marked by significant technological change, with associated risks escalating to systemic challenges at the societal level. He emphasized that AI power should not be concentrated in a few institutions and advocated for broader distribution through technological democratization and institutional constraints.
Addressing a recent incident where his residence was targeted with a Molotov cocktail, Altman admitted to underestimating the impact of public narratives and emotions amid AI-related anxieties. He also acknowledged mistakes in company governance and conflict management, offering apologies for past actions. Furthermore, Altman reiterated his decision to reject Elon Musk's attempts to control OpenAI, ensuring the company's independent development.
Previously, it was reported that the OpenAI founder's residence was attacked with a Molotov cocktail.
