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*.
