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
"PyDict_Check()".  The chapter is structured like the "family tree" of
Python object types.

警告: 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.
