Execute Bash commands Python way

Question

I am currently executing bash commands manually, by entering in shell in the python code.

How would one do this in the pythonic way?

i am currently using os.system function to execute commands like;

os.system('sudo add-apt-repository ppa:ondrej/php')
os.system('sudo apt-get update')
os.system('sudo apt-get install php7.0 php5.6 php5.6-mysql php-gettext php5.6-mbstring php-mbstring php7.0-mbstring php-xdebug libapache2-mod-php5.6 libapache2-mod-php7.0')
os.system('sudo a2dismod php7.0 ; sudo a2enmod php5.6 ; sudo service apache2 restart')

Use [subprocess](https://docs.python.org/3/library/subprocess.html) — Bubble Bubble Bubble Gut, Jan 02 '18 at 18:43

Possible duplicate of this question.

It is recommended to use subprocess module instead. os.system has been depreciated in favour of subprocess. For more information see subprocess documentation.

import subprocess

command = 'sudo add-apt-repository ppa:ondrej/php'
process = subprocess.Popen(command.split(), stdout=subprocess.PIPE)
output, error = process.communicate()

There's also the convience function in python 3 for getstatusoutput which is pretty nice. ` status, output = subprocess.getstatusoutput('cmd')` – Michael Mar 11 '20 at 18:44
