source code of python inbuilt functions [duplicate]

Question

I have used type() function in my program...

I just want to know how does Python implement this? Or where could I find the source code file that implement this function?

Answer 1

The type() function is implemented in C. Here's a link to the source: http://hg.python.org/cpython/file/0f837071fd97/Objects/typeobject.c

Answer 2

In general

import multiprocessing
multiprocessing.__path__
multiprocessing.__file__

__path__ yields location of the library __file__ yields complete path of the file.

If above didn't work, you need to look into python development source code.

Regarding type source code, Raymond Hettinger's answer is correct.
