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

虽然本章所描述的函数会仔细检查传入对象的类型,但是其中许多函数不会检查传入的对象是否为 NULL。 允许传入 NULL 可能导致内存访问冲突和解释器的立即终止。

Fundamental Objects

This section describes Python type objects and the singleton object None.
