Python + bash
Если вам часто требуется запускать shell команды из Python-кода, какой способ вы используете?
Самый низкоуровневый это функция os.system(), либо os.popen(). Рекомендованный способ это subprocess.call(). Но это всё еще достаточно неудобно.
Советую обратить своё внимание на очень крутую библиотеку sh.
Что она умеет?
🔸 удобный синтаксис вызова команд как функций
# os
import os
os.system("tar cvf demo.tar ~/")
# subprocess
import subprocess
subprocess.call(['tar', 'cvf', 'demo.tar', '~/'])
# sh
import sh
sh.tar('cvf', 'demo.tar', "~/")
🔸 простое создание функции-алиаса для длинной команды
fn = sh.lsof.bake('-i', '-P', '-n')
output = sh.grep(fn(), 'LISTEN')
в этом примере также задействован пайпинг
🔸 удобный вызов команд от sudo
with sh.contrib.sudo:
print(ls("/root"))
Такой запрос спросит пароль. Чтобы это работало нужно соответствующим способом настроить юзера.
А вот вариант с вводом пароля через код.
password = "secret"
sudo = sh.sudo.bake("-S", _in=password+"\n")
print(sudo.ls("/root"))
Это не все фишки. Больше интересных примеров смотрите в документации.

Smile is the only curve that sets things in straight line.
Harsh from Gujarat pens down a thought on smile...!!
Do you know what's satisfying?
When you make someone smile while they were crying.
That smile which holds fire to shine from within, But helplessness just dims their light within.
The smile that wants to burst out laughing,
But their situation insists them to shed another drop of tear.
We can just take a small initiative.
Don't show hatred towards anyone in their low
You never know, when that low might turn everything around.
If possible bring a smile on someone's face
The satisfaction you'll gain can't be expressed.
God's above seeing this, will smile too
And in your life you'll surely ace.
