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) #libs#basic

🪐 Spanning more than 300 light-years, a vast radio structure known as the "Orion Spur Radio Arc" weaves through our segment of the Milky Way. Detected by the LOFAR radio telescope, this arc is composed of incredibly energetic electrons spiraling around magnetic fields, revealing a hidden backbone of cosmic magnetism threading through our stellar neighborhood. ✨ #MilkyWay⚡#magnetism⚡#radio 👉subscribe Universe Mysteries

🌎 The mysterious Whistler waves are very low-frequency radio signals generated by lightning. They travel along Earth's magnetic field lines and can be converted to eerie whooshing or whistling sounds when played back as audio. These signals were first recorded by radio operators during World War I. ✨ #lightning⚡#magnetism⚡#radio 👉subscribe Interesting Planet ​

🪐 In the constellation Lynx lives an unusual star known as HD 45166, which has an incredibly strong magnetic field—about 43,000 times greater than Earth’s. This rare "magnetized helium star" shrouds itself in a thick, fast-moving wind of gas, and its unique magnetic properties provide astronomers with a rare look at how intense magnetism can shape the life and appearance of stars. ✨ #unusualstars⚡#magnetism⚡#astronomy⚡#nasa⚡#galaxy⚡#stars⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries ​

🪐 In the constellation Monoceros, the star HD 45166 is an unusually magnetic massive star with a surface magnetic field nearly 43,000 times stronger than Earth's. This extreme magnetism shapes the flow of gas around the star, producing powerful outflows and making HD 45166 a rare laboratory for studying the effects of magnetism on stellar evolution. ✨ #stars⚡#magnetism⚡#Monoceros⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries ​
