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.
- 
int PyBool_Check(PyObject *o)
- Return true if o is of type PyBool_Type. - 
New in version 2.3. 
- 
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.
- 
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.
- 
Py_RETURN_FALSE
- Return Py_False from a function, properly incrementing its reference
count. - 
New in version 2.4. 
- 
Py_RETURN_TRUE
- Return Py_True from a function, properly incrementing its reference
count. - 
New in version 2.4. 
- 
PyObject* PyBool_FromLong(long v)
- Return value: New reference.Return a new reference to Py_True or Py_False depending on the
truth value of v.
