.. data:: Unpack
A typing operator that conceptually marks an object as having been
unpacked. For example, using the unpack operator ``*`` on a
:class:`type variable tuple <TypeVarTuple>` is equivalent to using ``Unpack``
to mark the type variable tuple as having been unpacked::
A typing operator that conceptually marks an object as having been
unpacked. For example, using the unpack operator ``*`` on a
:class:`type variable tuple <TypeVarTuple>` is equivalent to using ``Unpack``
to mark the type variable tuple as having been unpacked::
Ts = TypeVarTuple('Ts')
tup: tuple[*Ts]
# Effectively does:
tup: tuple[Unpack[Ts]]
Ts = TypeVarTuple('Ts')
tup: tuple[*Ts]
# Effectively does:
tup: tuple[Unpack[Ts]]
In fact, ``Unpack`` can be used interchangeably with ``*`` in the context
of types. You might see ``Unpack`` being used explicitly in older versions
of Python, where ``*`` couldn't be used in certain places::
