.. highlightlang:: c .. _boolobjects: Boolean Objects --------------- Booleans in Python are implemented as a subclass of integers. There are only two booleans, :const:`Py_False` and :const:`Py_True`. As such, the normal creation and deletion functions don't apply to booleans. The following macros are available, however. .. c:function:: int PyBool_Check(PyObject *o) Return true if *o* is of type :c:data:`PyBool_Type`. .. versionadded:: 2.3 .. c:var:: PyObject* Py_False The Python ``False`` object. This object has no methods. It needs to be treated just like any other object with respect to reference counts. .. c:var:: PyObject* Py_True The Python ``True`` object. This object has no methods. It needs to be treated just like any other object with respect to reference counts. .. c:macro:: Py_RETURN_FALSE Return :const:`Py_False` from a function, properly incrementing its reference count. .. versionadded:: 2.4 .. c:macro:: Py_RETURN_TRUE Return :const:`Py_True` from a function, properly incrementing its reference count. .. versionadded:: 2.4 .. c:function:: PyObject* PyBool_FromLong(long v) Return a new reference to :const:`Py_True` or :const:`Py_False` depending on the truth value of *v*. .. versionadded:: 2.3
