Some named tuples are built-in types (such as the above examples).
Alternatively, a named tuple can be created from a regular class
definition that inherits from :class:`tuple` and that defines named
- fields. Such a class can be written by hand or it can be created with
- the factory function :func:`collections.namedtuple`. The latter
- technique also adds some extra methods that may not be found in
- hand-written or built-in named tuples.
