7.2.2 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): Returns 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.

int PyBool_FromLong( long v): Returns Py_True or Py_False depending on the truth value of v. New in version 2.3.
