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.

🔴 Today I suggest you plunge into the past and visit the mill, which is 130 years old!
Pflaumer's Mill is a wooden giant on the banks of the Volga
On the left bank of the Volga, a little away from the city of Nikolaevsk, a huge wooden steam mill of the late XIX - early XX century has been standing for more than a century. It is called the "Pfläumer Mill" in honor of the German settler Friedrich Pfläumer. They say that he built it in 1906, although according to other sources he was only a co-owner and manager.

🔴 Today I would like to invite you to a most unusual temple.
The Temple of All Religions in Kazan
This temple is not about prayers. Services are not held here, and believers are not gathered here. It is more of a museum, a symbol, a fantasy about world religions.

🔴 Moscow has many different architectural styles and trends in construction. You can, for example, find a piece of Italy.
Tarasov's mansion is a true oasis of the Italian Renaissance amidst the bustle of Moscow. It was built at the beginning of the 20th century: the project was ordered by Gavriil Tarasov, a Moscow merchant.
The idea was ambitious: Gabriel wanted a house that looked like a palazzo in Vicenza (a city in Italy), and architect Zholtovsky did not disappoint. He created a true Italian palace that you would hardly expect in the very center of Moscow — marble, columns, arches.

🔴 I invite you to a walk around amazing Karelia.
Sortavala is a Karelian city with a European soul and a long history.
A bit of history
The city was officially founded in 1468, although people lived here long before that date. The first settlers were the Sami, an ancient people of the North. Archaeologists find bone needles, arrowheads, and the remains of settlements of the II millennium BC on the islands. Throughout its history, Sortavala has changed hands more than once: from Russia to Sweden, back to Russia, then to Finland and back again. Each era has left its traces in the appearance of the city.
