14.3.3.8 Querying and manipulating your option parser

Sometimes, it's useful to poke around your option parser and see what'sthere. OptionParser provides a couple of methods to help you out:

has_option(opt_str)

Return true if the OptionParser has an option with option stringopt_str (e.g.,-q or--verbose).

get_option(opt_str)

Returns the Option instance with the option stringopt_str, orNone if no options have that option string.

remove_option(opt_str)

If the OptionParser has an option corresponding toopt_str,that option is removed. If that option provided any otheroption strings, all of those option strings become invalid.Ifopt_str does not occur in any option belonging to thisOptionParser, raises ValueError.
