Making a system call that returns the stdout output as a string

by

Python

from subprocess import check_output as qx

output = qx(['ls', '-lt'])

Python <2.7 or <3.1

Extract subprocess.check_output() from subprocess.py or adapt something similar to:

import subprocess

def cmd_output(args, **kwds):
  kwds.setdefault("stdout", subprocess.PIPE)
  kwds.setdefault("stderr", subprocess.STDOUT)
  p = subprocess.Popen(args, **kwds)
  return p.communicate()[0]

print cmd_output("ls -lt".split())

The subprocess module has been in the stdlib since 2.4.
