An example of running a shell command from python and capturing its output.

example.py

import subprocess

MyOut = subprocess.Popen(['ls', '-l', '.'], 
            stdout=subprocess.PIPE, 
            stderr=subprocess.STDOUT)

stdout,stderr = MyOut.communicate()

if stdout:
    print(stdout.decode('utf-8'))
  
if stderr:
    print(stderr.decode('utf-8'))

The original code for this was taken from https://linuxhandbook.com/execute-shell-command-python/

Note that you can specify the encoding in the call instead of decoding it after:

MyOut = subprocess.Popen(['ls', '-l', '.'], 
            stdout=subprocess.PIPE, 
            stderr=subprocess.STDOUT,
            encoding='utf8')
