Hi dear all,=20

I have following Python code

def __init__(self):

I wonder how this new type get created . What is the type of metatype = in the following line ?

type =3D (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!!!
