+.. c:function:: Py_ssize_t PyObject_LengthHint(PyObject *o, Py_ssize_t defaultvalue)
Return an estimated length for the object *o*. First try to return its
actual length, then an estimate using :meth:`~object.__length_hint__`, and
finally return the default value. On error return ``-1``. This is the
- equivalent to the Python expression ``operator.length_hint(o, default)``.
