Boolean オブジェクト

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

次に属します: Stable ABI.

この PyTypeObject のインスタンスは Python の boolean 型を表現します; Python レイヤにおける bool と同じオブジェクトです。

int PyBool_Check(PyObject *o)

o が PyBool_Type 型の場合に真を返します。この関数は常に成功します。

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.

Py_RETURN_TRUE

Return Py_True from a function, properly incrementing its reference count.

PyObject *PyBool_FromLong(long v)

戻り値: 新しい参照。 次に属します: Stable ABI.

Return a new reference to Py_True or Py_False depending on the truth value of v.
