I am not a big user of python, hence the username, however I used the
os.popen command as suggested by Rikard

In the shell:

data = os.popen('ls')
type(data)
    <type 'file'>
Then a loop over the data object
for f in data:
    print f

seemed to do the job.

I did notice that I could not capture the information to a var using the
subprocess call - I HAVE NOT READ THE DOCs (yet) - a quick look suggested
that this *should* work

The call I made using subprocess
from subprocess import call
foo = call("ls")
  <PRINTS CONTENTS OF /HOME/>
  <FOO IS == 0 >
