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.

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. 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)

Return value: New reference. Part of the Stable ABI.

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