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 :)

To add to urschrei's answer, here's an example (Windows):
>>> import subprocess
>>> p = subprocess.Popen(['ping', '192.168.111.198'], stdout=subprocess.PIPE, st
derr=subprocess.PIPE)
>>> out, err = p.communicate()
>>> print out

You're looking for the subprocess module, specifically the subprocess.check_call() and/or subprocess.check_output() commands.

For backward-compatibility, you might want to be a bit careful with
check_output, which is only on >=2.7. Before 2.7, you probably need to use Popen with subprocess.PIPE
