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.
