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.
[!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
NULLbeing passed instead of a valid object. AllowingNULLto be passed in can cause memory access violations and immediate termination of the interpreter.
Fundamental Objects
This section describes Python type objects and the singleton object None.
type.rst none.rst
Numeric Objects
pair: object; numeric
long.rst bool.rst float.rst complex.rst
Sequence Objects
pair: object; sequence
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.
bytes.rst bytearray.rst unicode.rst tuple.rst list.rst
Container Objects
pair: object; mapping
dict.rst set.rst
Function Objects
function.rst method.rst cell.rst code.rst
Other Objects
