A tuple field, composed of a fixed number of other `Field` classes or
instances
Example: ::
row = Tuple((fields.String(), fields.Integer(), fields.Float()))
.. note::
Because of the structured nature of `collections.namedtuple` and
`typing.NamedTuple`, using a Schema within a Nested field for them is
more appropriate than using a `Tuple` field.
:param Iterable[Field] tuple_fields: An iterable of field classes or
instances.
:param kwargs: The same keyword arguments that :class:`Field` receives.
.. versionadded:: 3.0.0rc4
