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.

PyTypeObject PyBool_Type

Parte del ABI Stabile.

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.

PyObject *Py_False

The Python False object. This object has no methods and is immortal.

Cambiato nella versione 3.12: Py_False is immortal.

PyObject *Py_True

The Python True object. This object has no methods and is immortal.

Cambiato nella versione 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)

Valore di ritorno: Nuovo riferimento. Parte del ABI Stabile.

Return Py_True or Py_False, depending on the truth value of v.
