This document is for an old version of Python that is no longer supported.
You should upgrade and read the
Python documentation for the current stable release.
The None
Object¶
Note that the PyTypeObject
for None
is not directly exposed in the
Python/C API. Since None
is a singleton, testing for object identity (using
==
in C) is sufficient. There is no PyNone_Check()
function for the
same reason.
