Perhaps you're looking for the subprocess.check_output function? See the subprocess module for more details.

The subprocess module is the "new supported python way"---yeah, os.popen is my favorite too.

or you could use

os.system('a_command > file')
with open('file','r') as cmdoutput:
cmdoutput.readlines()
