Boolean Objects

Python documentation

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.

intPyBool_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

.

Changed in version 3.12:

Py_False

is

immortal

.

PyObject

*Py_True

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

immortal

.

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(longv)

Return value: New reference. Part of the

Stable ABI

.Return

Py_True

or

Py_False

, depending on the truth value of v.
