How to "apt full-upgrade" using a python script

Question

I want to be able to 1) upgrade my RPi via python and 2) catch the results (as String) to see how things went. How can I do it passing also automatically any relevant -Y responses.

Answer 1

I eventually ended up using:

command = ['apt', 'full-upgrade', '-y']
result = str(subprocess.run(command, capture_output=True).stdout, 'ascii')
