Question

I have experience with perl for writing scripts, which made it easy for me executing linux commands by using back-ticks. I was wondering, how can I do this Python ? Is there a special way for capturing the result of a command (output) ?

thank you 🙂

>>> import subprocess
>>> p = subprocess.Popen(['ping', '192.168.111.198'], stdout=subprocess.PIPE, st
derr=subprocess.PIPE)
>>> out, err = p.communicate()
>>> print out
