This is the equivalent of the Python expression ``hash(o)``.
.. cfunction:: long PyObject_HashNotImplemented(PyObject *o)
Set a TypeError indicating that ``type(o)`` is not hashable and return ``-1``.
This function receives special treatment when stored in a ``tp_hash`` slot,
allowing a type to explicit indicate to the interpreter that it is not
hashable.
.. versionadded:: 2.6
.. cfunction:: int PyObject_IsTrue(PyObject *o)
Returns ``1`` if the object *o* is considered to be true, and ``0`` otherwise.
