   Bases: :py:obj:`argparse.Action`


   Information about how to convert command line strings to Python objects.

   Action objects are used by an ArgumentParser to represent the information
   needed to parse a single argument from one or more strings from the
   command line. The keyword arguments to the Action constructor are also
   all attributes of Action instances.

   Keyword Arguments:

       - option_strings -- A list of command-line option strings which
           should be associated with this action.

       - dest -- The name of the attribute to hold the created object(s)

       - nargs -- The number of command-line arguments that should be
           consumed. By default, one argument will be consumed and a single
           value will be produced.  Other values include:
               - N (an integer) consumes N arguments (and produces a list)
               - '?' consumes zero or one arguments
               - '*' consumes zero or more arguments (and produces a list)
               - '+' consumes one or more arguments (and produces a list)
           Note that the difference between the default and nargs=1 is that
           with the default, a single value will be produced, while with
           nargs=1, a list containing a single value will be produced.

       - const -- The value to be produced if the option is specified and the
           option uses an action that takes no values.

       - default -- The value to be produced if the option is not specified.

       - type -- A callable that accepts a single string argument, and
           returns the converted value.  The standard Python types str, int,
           float, and complex are useful examples of such callables.  If None,
           str is used.

       - choices -- A container of values that should be allowed. If not None,
           after a command-line argument has been converted to the appropriate
           type, an exception will be raised if it is not a member of this
           collection.

       - required -- True if the action must always be specified at the
           command line. This is only meaningful for optional command-line
           arguments.

       - help -- The help string describing the argument.

       - metavar -- The name to be used for the option's argument with the
           help string. If None, the 'dest' value will be used as the name.
