6.21.3.5 Querying and manipulating your option parser

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

has_option(opt_str)

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

get_option(opt_str)

Returns the Option instance with the option string opt_str, or None if no options have that option string.

remove_option(opt_str)

If the OptionParser has an option corresponding to opt_str, that option is removed. If that option provided any other option strings, all of those option strings become invalid.

If opt_str does not occur in any option belonging to this OptionParser, raises ValueError.
