Constantly print Subprocess output while process is running

by

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

def execute(command):
    process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    output = process.communicate()[0]
    exitCode = process.returncode

    if (exitCode == 0):
        return output
    else:
        raise ProcessException(command, exitCode, output)

So when i launch a process like Process.execute("mvn clean install"), my program waits until the process is finished, and only then i get the complete output of my program. This is annoying if i’m running a process that takes a while to finish.

Can I let my program write the process output line by line, by polling the process output before it finishes in a loop or something?

I found this article which might be related.
