Constantly print Subprocess output while process is running

Question

To launch programs from my Python-scripts, I\'m using the following method:

def execute(command):
    process = subprocess.Popen(command, shell=True, stdout=s         


        

Answer 1

There is actually a really simple way to do this when you just want to print the output:

import subprocess
import sys

def execute(command):
    subprocess.check_call(command, stdout=sys.stdout, stderr=subprocess.STDOUT)

Here we're simply pointing the subprocess to our own stdout, and using existing succeed or exception api.
