Below is the output you had asked,

>>> import subprocess as sub
>>> p = sub.Popen('ls',stdout=sub.PIPE,stderr=sub.PIPE)
>>> output, errors = p.communicate()
>>> print output

>>> import subprocess as sub
>>> p = sub.Popen('ls',stdout=sub.PIPE,stderr=sub.PIPE)
>>> output, errors = p.communicate()
>>> print errors

>>> import subprocess
>>> status = subprocess.call("ls"+ "", shell=True)
>>> print status
255

in the first two cases, output and errors both are coming empty where as subprocess.call returns 255 again.
