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)

My First Encounter With Death-:
I was then a Puerilo of Around 6 & Studied in U.K.G or Perhaps L.K.G,
I used to go to School on Foot.
On My Way to School and Back To Home , I did See an Old Man
He was a Hindu & Perhaps A Brahmin Sitting on a Khatola Out his House
Looking me He did Send a Smile
And this Scene was not a Talk of Someday ,A Year Passed that way
Never I gone near Him ,Neither I ever Sent him That Smile Back
He was After all a Stranger
A REGULAR STRANGER
Then a Day On My Way Back Home , I Saw Crowd Out his House
He was Made Sleep on Ground
And was Draped with White Cloth
Then A Moment Next People Lifted him up on Some Woody-Arrangement & Started Saying
‘’RAAM NAAM SATYA HAI ......
RAAM NAAM SATYA HAI......’’
I Understood Nothing Yet I get Blank , My Neck Got Dried , My Blood Felt-like Freezed, My Body Stiffened , I was Suffocating
A Horror and Pain Sticken To My Heart & I Started Crying to My Fullest on my way
Even Some People of My Dada-Abbu’s Pehchaan stopped & Asked me ‘’ Kaa Hua Babua Kahen Rovat Hey ‘’ But I just Cried
I reached Home My Daadi , My Phupphi , My Ammi & My Par-Daadi all tried to Stop me from Sobbing but i myself was not having Control over it , it was Coming itself
I Cried and just Cried till i got into Grip of Sleep
I Caught High Fever ,
loose-Motions , Vomitting and just wht not
I had not Gone School For 5-6 Days .
When I resumed my Schooling then on that way
No More a Person In Vest & Dhoti
With a Smile to Greet Sits On Khatola Out There On That ‘Chabotra’ [A Raised Land]
I did Send Smile Back Daily
Paying The Debt I Owe to Someone
But None To Receive.......

Part 2: Babur, at age 13, wrote in the Baburnama about his feelings for a boy named Baburi:
> “In those leisurely days, I discovered in myself a strange inclination — nay! as the verse says, ‘I maddened and afflicted myself’ — for a boy in the camp‑bazar, his very name, Bāburī, fitting in. Up till then I had had no inclination for anyone… From time to time Bāburi came to my presence but out of modesty I could never look straight at him… I got so confused that I almost went right off.”

Note: this does not mean he was homosexual. Such feelings can be a normal part of teenage self-discovery.
