I think I've found it out . For new-style class it's PyType_Type and for old-style class it's PyClass_Type . Thanks anyway.

Hi dear all, 
I have following Python code
class mydict(dict):
    def __init__(self):
        pass
I wonder how this new type get created . What is the type of metatype in the following line ?
type = (PyTypeObject *)metatype->tp_alloc(metatype, nslots);
(line 2296 of typeobject.c Python2.7.3 source code)
It seems PyDict_Type . If so , how do I expect the tp_alloc will return a PyTypeObject object ? Maybe I've missed something ?
Many thanks!!!
