Ever wondered how Python works under the hood? One way to learn about
Python-the-C-program is by exploring the C API for writing Python
bindings to native C libraries. In this talk, we will walk through a
simple example of making a C library callable from Python code and
vice versa. Along the way, we will encounter some essential features
of Python: reference counting, memory management, and the inner-
workings of objects and modules.

We all love Python. It’s so elegant and easy to use as a programming
language that we forget about the giant, complicated C program
executing our strings of white-space sensitive code. For many Python
programmers, this side of Python is just a big black box. It works
well, so thankfully we don’t need to go messing around inside... but
what if you want to look into the inner workings of this powerful
tool? One way to dive into the C-program-side of Python is by
exploring the C API for writing Python bindings to native C libraries.
In this talk I will explore the basics of this API as I recount my
journey to make a simple C library callable from Python code, and
allow C code to invoke objects defined in pure Python. Along the way,
we will encounter some essential features of Python: reference
counting, memory management, and the inner-workings of objects and
modules.
