optparse is deprecated, from 
https://docs.python.org/3/library/optparse.html "Deprecated since 
version 3.2: The optparse module is deprecated and will not be developed 
further; development will continue with the argparse module".  argparse 
is here https://docs.python.org/3/library/argparse.html

There are also the third party modules docopt 
https://github.com/docopt/docopt which is excellent and clize 
https://github.com/epsy/clize which I've never tried.
