**********************
Concrete Objects Layer
**********************
The functions in this chapter are specific to certain Python object types.
Passing them an object of the wrong type is not a good idea; if you receive an
object from a Python program and you are not sure that it has the right type,
you must perform a type check first; for example, to check that an object is a
dictionary, use :cfunc:`PyDict_Check`. The chapter is structured like the
"family tree" of Python object types.
.. warning::
While the functions described in this chapter carefully check the type of the
objects which are passed in, many of them do not check for *NULL* being passed
instead of a valid object. Allowing *NULL* to be passed in can cause memory
access violations and immediate termination of the interpreter.

Sequence Objects
================

Generic operations on sequence objects were discussed in the previous chapter;
this section deals with the specific kinds of sequence objects that are
intrinsic to the Python language.
