I'd like to study the CPython implementations of lists and array.array instances for a personal project of mine, but I've very unfamiliar with the Python source code as it pertains to internals like this. Which files would I need to look at to do this,

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

and are there a few particular functions/structures I should pay attention to? I'm just looking for a brief pointer in the right direction here, not a full explanation of how it works -- I'll get that from studying the source code. :-)
