+.. method:: ArgumentParser.register(registry_name, value, object)
+
+   Sometimes it's desirable to use a custom string in error messages to provide
+   more user-friendly output. In these cases, :meth:`!register` can be used to
+   register custom actions or types with a parser and allow you to reference the
+   type by their registered name instead of their callable name.
+
+   The :meth:`!register` method accepts three arguments - a *registry_name*,
+   specifying the internal registry where the object will be stored (e.g.,
+   ``action``, ``type``), *value*, which is the key under which the object will
+   be registered, and object, the callable to be registered.
+
+   The following example shows how to register a custom type with a parser::
+
+      >>> import argparse
+      >>> parser = argparse.ArgumentParser()
+      >>> parser.register('type', 'hexadecimal integer', lambda s: int(s, 16))
+      >>> parser.add_argument('--foo', type='hexadecimal integer')
+      _StoreAction(option_strings=['--foo'], dest='foo', nargs=None, const=None, default=None, type='hexadecimal integer', choices=None, required=False, help=None, metavar=None, deprecated=False)
