# 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.
