Boolean Objects¶
Booleans in Python are implemented as a subclass of integers.  There are only
two booleans, Py_False and Py_True.  As such, the normal
creation and deletion functions don’t apply to booleans.  The following macros
are available, however.
- 
PyTypeObject PyBool_Type¶
-  Part of the Stable ABI.This instance of PyTypeObjectrepresents the Python boolean type; it is the same object asboolin the Python layer.
- 
int PyBool_Check(PyObject *o)¶
- Return true if o is of type - PyBool_Type. This function always succeeds.
- 
PyObject *Py_False¶
- The Python - Falseobject. This object has no methods. It needs to be treated just like any other object with respect to reference counts.
- 
PyObject *Py_True¶
- The Python - Trueobject. This object has no methods. It needs to be treated just like any other object with respect to reference counts.
- 
Py_RETURN_FALSE¶
- Return - Py_Falsefrom a function, properly incrementing its reference count.
- 
Py_RETURN_TRUE¶
- Return - Py_Truefrom a function, properly incrementing its reference count.
- 
PyObject *PyBool_FromLong(long v)¶
- Return value: New reference. Part of the Stable ABI.Return a new reference to Py_TrueorPy_Falsedepending on the truth value of v.
