Built-in objects are usually in the Objects/ directory, with a
corresponding include file in the Include/ directory:
https://hg.python.org/cpython/file/default/Objects/listobject.c
https://hg.python.org/cpython/file/default/Include/listobject.h

Modules implemented in C are usually in the Modules/ directory:
https://hg.python.org/cpython/file/default/Modules/arraymodule.c
