Finding the source code for built-in Python functions?

Question

Is there a way to see how built in functions work in python? I don\'t mean just how to use them, but also how were they built, what is the code behind sorted

Answer 1

I had to dig a little to find the source of the following Built-in Functions as the search would yield thousands of results. (Good luck searching for any of those to find where it's source is)

Anyway, all those functions are defined in bltinmodule.c Functions start with builtin_{functionname}

Built-in Source: https://github.com/python/cpython/blob/master/Python/bltinmodule.c

For Built-in Types: https://github.com/python/cpython/tree/master/Objects
