Abstract Objects Layer

**********************

The functions in this chapter interact with Python objects regardless of their

type, or with wide classes of object types (e.g. all numerical types, or all

sequence types).  When used on object types for which they do not apply, they

will raise a Python exception.

It is not possible to use these functions on objects that are not properly

initialized, such as a list object that has been created by :cfunc:`PyList_New`,

but whose items have not been set to some non-\ ``NULL`` value yet.
