+The Namespace object
+^^^^^^^^^^^^^^^^^^^^
+
+By default, :meth:`parse_args` will return a new object of type :class:`Namespace`
+where the necessary attributes have been set. This class is deliberately simple,
+just an :class:`object` subclass with a readable string representation. If you
+prefer to have dict-like view of the attributes, you can use the standard Python
+idiom via :func:`vars`::
+
+ >>> parser = argparse.ArgumentParser()
+ >>> parser.add_argument('--foo')
+ >>> args = parser.parse_args(['--foo', 'BAR'])
+ >>> vars(args)
+ {'foo': 'BAR'}
It may also be useful to have an :class:`ArgumentParser` assign attributes to an
-already existing object, rather than the newly-created :class:`Namespace` object
-that is normally used. This can be achieved by specifying the ``namespace=``
-keyword argument::
