Boolean Objects (original) (raw)
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.
PyTypeObject PyBool_Type¶
Part of the Stable ABI.
This instance of PyTypeObject represents the Python boolean type; it is the same object as bool in the Python layer.
int PyBool_Check(PyObject *o)¶
Return true if o is of type PyBool_Type. This function always succeeds.
The Python False
object. This object has no methods and isimmortal.
Changed in version 3.12: Py_False is immortal.
The Python True
object. This object has no methods and isimmortal.
Changed in version 3.12: Py_True is immortal.
Py_RETURN_FALSE¶
Return Py_False from a function.
Py_RETURN_TRUE¶
Return Py_True from a function.
PyObject *PyBool_FromLong(long v)¶
Return value: New reference. Part of the Stable ABI.
Return Py_True or Py_False, depending on the truth value of v.
