python read dynamic stdout process

Question

i try to read dynamic airodump-ng stdout with python, example process output -> https://i.makeagif.com/media/8-22-2015/EgkrBx.gif

i'm already to get output as text file, but the result is not in real time, so i try to directly read the stdout

import subporcess
subprocess.getoutput("timeout 10 airodump-ng args")

expected result :

run command and get real time output of called process stdout
