How to get process' status from python code?

I'd like to operate a process using supervisorctl from python code, in order to get the status and make conditional branches like this: 

import subprocess

status = subprocess.run(["sudo", "supervisorctl", "status", "my_process"])
if status == "STOPPED":
    # Do something
else:
    # Do another thing

But this doesn't work. subprocess.run returns CompletedProcess(args=['sudo', 'supervisorctl', 'status', 'my_status'], returncode=0). The response doesn't have what the status is.
Is there any way to get the status?

Solution

  • I think you need to use subprocess.check_output() to get the output returned to you rather than just the return code. 

    subprocess.check_output(args, *, stdin=None, stderr=None, shell=False, universal_newlines=False)

    Run command with arguments and return its output as a byte string.
