by Jan Kaliszewski. Besides providing an :term:`abstract base class` for
|
||||
named tuples, it also supports an alternate :term:`metaclass`-based
|
||||
constructor that is convenient for use cases where named tuples are being
|
||||
subclassed.

* See :class:`typing.NamedTuple` for a way to add type hints for named

tuples. It also provides an elegant notation using the :keyword:`class`

keyword::

class Component(NamedTuple):
|

part_number: int
|

weight: float

description: Optional[str] = None

* See :meth:`types.SimpleNamespace` for a mutable namespace based on an

underlying dictionary instead of a tuple.

|

* See :meth:`typing.NamedTuple` for a way to add type hints for named tuples.
|

* The :mod:`dataclasses` module provides a decorator and functions for
|
||||
automatically adding generated special methods to user-defined classes.
