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.

🌍 Earth's crust is in constant motion due to convection currents—slow, swirling movement of hot rock deep below the surface. This drives plate movement, causing earthquakes and forming new land. ✨ #processes⚡#plate⚡#tectonics⚡#geology⚡#geography⚡#nature⚡#earth 👉subscribe Amazing Geography🌍

https://docs.python.org/3/library/subprocess.html The #subprocess module allows you to spawn new #processes, connect to their input/output/error pipes, and obtain their return codes. This module intends to replace several older #modules and #functions. #python

https://pymotw.com/3/asyncio/executors.html Combining Coroutines with Threads and Processes A lot of existing libraries are not ready to be used with #asyncio natively. They may block, or depend on concurrency features not available through the module. It is still possible to use those libraries in an application based on asyncio by using an #executor from #concurrent.futures to run the code either in a separate thread or a separate process. #Threads The #run_in_executor() method of the event loop takes an executor instance, a regular callable to invoke, and any arguments to be passed to the callable. It returns a Future that can be used to wait for the function to finish its work and return something. If no executor is passed in, a #ThreadPoolExecutor is created. This example explicitly creates an executor to limit the number of worker threads it will have available. #Processes A ProcessPoolExecutor works in much the same way, creating a set of worker #processes instead of threads. Using separate processes requires more system resources, but for computationally-intensive operations it can make sense to run a separate task on each CPU core. #learn
