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
orPy_False
depending on the truth value of v.New in version 2.3.
