Boolean Objects
---------------
Booleans in Python are implemented as a subclass of integers. There are only
two booleans, :c:data:`Py_False` and :c:data:`Py_True`. As such, the normal
creation and deletion functions don't apply to booleans. The following macros
are available, however.
.. c:var:: PyTypeObject PyBool_Type
This instance of :c:type:`PyTypeObject` represents the Python boolean type; it
is the same object as :class:`bool` in the Python layer.
.. c:function:: int PyBool_Check(PyObject *o)
Return true if *o* is of type :c:data:`PyBool_Type`. This function always
succeeds.
.. c:var:: PyObject* Py_False
The Python ``False`` object. This object has no methods and is
:term:`immortal`.
.. versionchanged:: 3.12
:c:data:`Py_False` is :term:`immortal`.
.. c:var:: PyObject* Py_True
The Python ``True`` object. This object has no methods and is
:term:`immortal`.
.. versionchanged:: 3.12
:c:data:`Py_True` is :term:`immortal`.
.. c:macro:: Py_RETURN_FALSE
Return :c:data:`Py_False` from a function.
.. c:macro:: Py_RETURN_TRUE
Return :c:data:`Py_True` from a function.
.. c:function:: PyObject* PyBool_FromLong(long v)
Return :c:data:`Py_True` or :c:data:`Py_False`, depending on the truth value of *v*.
