You don't; os.system is only usable to send commands off that need no input
and which you don't care for the output. Check out the subprocess module.

You can do like:

popen = subprocess.Popen("whoami", stdout=subprocess.PIPE)

Then "out, err = popen.communicate()"

The 'out' should contain the output from the command.
