You should use the subprocess module to deal with external commands.

>>> import subprocess
>>> s = subprocess.Popen(["head", "/etc/hosts"], stdout = subprocess.PIPE)
>>> hosts_head = s.stdout.read()
>>> print hosts_head
127.0.0.1       localhost

[...]

Use that get your output and then parse it with the regexp.
