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.

Breaking: A Boeing 737 plane that plummeted into a Chinese hillside in 2022, killing all 132 people on board, had its fuel supply cut mid-flight, according to newly released data by the US National Transportation Safety Board (NTSB).
Findings by the NTSB say that the fuel switches on both engines of the China Eastern flight were moved to the "cut-off" position while it was at a cruising altitude of 8,839m (29,000ft) — exactly like the AI171 Air India crash in Gujarat last year.
China has yet to release a final report on the incident, citing national security concerns. #Aviation

GPS Renewables started construction on India's first Ethanol-to-Jet (ETJ) Sustainable Aviation Fuel (SAF) plant in Pudimadaka, Andhra Pradesh, under an NTPC Green Energy EPC contract. Using Lummus Technology and Xytel India's engineering, the facility at NTPC's Green Hydrogen Hub will produce 1,800 tonnes per annum of SAF and renewable diesel. The process converts CO2-derived ethanol via ethylene conversion, oligomerisation, and hydroprocessing. This project advances India's sustainable aviation fuel scaling and transport sector decarbonization goals.
