When used on object types for which they do not apply, they 12will raise a Python exception. 13 14It is not possible to use these functions on objects that are not properly 15initialized, such as a list object that has been created by :c:func:`PyList_New`, 16but whose items have not been set to some non-\ ``NULL`` value yet. 17 18.. toctree:: 19 20 object.rst 21 number.rst 22 sequence.rst 23 mapping.rst 24 iter.rst 25 buffer.rst 26 objbuffer.rst 27
