We all know Python is a bytecode interpreter, but what does that mean? Come find out! You'll learn what Python bytecodes are, what they do, and even how you can tinker with them. By the end of the talk you'll be an expert. All code will be 100% Python 3--knowledge of C not required!

Ever wondered how CPython actually works internally? This talk will show you. We start with a simple Python program, then slowly step through CPython, showing in exhaustive detail what happens when it runs that program. Along the way we'll examine the design and implementation of various major CPython subsystems and see how they fit together. The audience should be conversant in C and Python.
