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.

🇮🇳 On September 2, Ratish Nair, Honorary Consul of Russia in Trivandrum (Karnataka, India), began a journey along the route of Afanasy Nikitin. The ambitious project is dedicated to the 555th anniversary of the famous "Journey Beyond Three Seas".
📍 The starting point of the journey was the embankment named after the famous Russian traveler Afansy Nikitin in Tver.
⚡️ Ratish Nair met Senator of the Federation Council of Russia from the Tver Region Lyudmila Skakovskaya and Rector of Tver State University Sergei Smirnov.
I am sure that this is a wonderful undertaking - repeating the route of the Tver merchant Afanasy Nikitin. This will help educational and outreach work, draw attention to the traveler's personality, and strengthen ties between our countries. I am sure that in our country, preserving and studying history is one of the most important areas of work,
the Senator emphasized.
Even in India, not everyone knows that Afanasy Nikitin is the first foreigner who came to our country for peaceful purposes. Friendly relations between India and Russia should be strengthened. This is the main goal of my trip. I am sure that the trip, repeating the path of the Russian traveler, will help to show Russia as it is and open it to foreigners without speculation and fakes,
said Ratish Nair.
🗣The meeting participants discussed the opening of Russian online educational courses in Russian in the Indian state of Karnataka, as well as other educational initiatives.
🗺 The head of the Russian House in Trivandrum will visit four more countries after Russia. His route, like 555 years ago, will lie from Tver to Astrakhan along the Volga river, then by car to Derbent, from there to
🇦🇿Azerbaijan, then to
🇮🇷 Iran, from there by plane to
🇴🇲 Oman, and then to
🇮🇳 India.
This project is organized by #Rossotrudnichestvo, the Russian Ministry of Foreign Affairs (#MFA), the #RusskiyMirFoundation, and the Russian Geographical Society (#RGS, #RGO), with #Rosatom and #Sber as partners.
