This document is for an old version of Python that is no longer supported. You should upgrade, and read the Python documentation for the current stable release.

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.

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.

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