When used on object types for which they do not apply, they 13will raise a Python exception. 14 15It is not possible to use these functions on objects that are not properly 16initialized, such as a list object that has been created by :c:func:`PyList_New`, 17but whose items have not been set to some non-\ ``NULL`` value yet. 18 19.. toctree:: 20 21 object.rst 22 number.rst 23 sequence.rst 24 mapping.rst 25 iter.rst 26 objbuffer.rst 27
