Boolean Objects¶

Booleans in Python are implemented as a subclass of integers. There are onlytwo booleans,Py_False andPy_True. As such, the normalcreation and deletion functions don’t apply to booleans. The following macrosare available, however.

PyTypeObjectPyBool_Type¶

Part of theStable ABI.

This instance ofPyTypeObject represents the Python boolean type; itis the same object asbool in the Python layer.

intPyBool_Check(PyObject*o)¶

Return true ifo is of typePyBool_Type. This function alwayssucceeds.

PyObject*Py_False¶

The PythonFalse object. This object has no methods. It needs to betreated just like any other object with respect to reference counts.

PyObject*Py_True¶

The PythonTrue object. This object has no methods. It needs to be treatedjust like any other object with respect to reference counts.

Py_RETURN_FALSE¶

ReturnPy_False from a function, properly incrementing its referencecount.

Py_RETURN_TRUE¶

ReturnPy_True from a function, properly incrementing its referencecount.

PyObject*PyBool_FromLong(longv)¶

Return value: New reference. Part of theStable ABI.

Return a new reference toPy_True orPy_False depending on thetruth value ofv.
