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) |
-
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.
New in version 2.3.
Release 2.4.5, documentation updated on 18 October 2006.
