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.
|
||
|
|
|
||
|
|
|
||
|
|
.. cfunction:: int PyBool_Check(PyObject *o)
|
||
|
|
|
||
|
|
Return true if *o* is of type :cdata:`PyBool_Type`.
|
||
|
|
|
||
|
|
|
||
|
|
.. cvar:: 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.
|
||
|
|
|
||
|
|
|
||
|
|
.. cvar:: 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.
|
||
|
|
|
||
|
|
|
||
|
|
.. cmacro:: Py_RETURN_FALSE
|
||
|
|
|
||
|
|
Return :const:`Py_False` from a function, properly incrementing its reference
|
||
|
|
count.
|
||
|
|
|
||
|
|
|
||
|
|
.. cmacro:: Py_RETURN_TRUE
|
||
|
|
|
||
|
|
Return :const:`Py_True` from a function, properly incrementing its reference
|
||
|
|
count.
|
||
|
|
|
||
|
|
|
||
|
|
.. cfunction:: PyObject* PyBool_FromLong(long v)
|
||
|
|
|
||
|
|
Return a new reference to :const:`Py_True` or :const:`Py_False` depending on the
|
||
|
|
truth value of *v*.
