If all you want to do is execute the program, and not capture the
output, then the os.system() command is what you need, eg:
>>> import os
>>> args = '-lG /usr/X11R6/'
>>> os.system('ls %s' % (args, ))
total 11

If however you need to capture the programs output, you will need to
have a look at the popen2 module, which I am not to familiar with so
cannot provide an example.
