Bytecode, the internal language of instructions used by the interpreter is something that perhaps most Python developers have heard about, but few have dug into. This talk will try to explain the idea behind bytecode and how it works.
We will see how to extract bytecode from functions - with dis module, and from .pyc files (and what is the idea of __pycache__ directories). Then, the other way around: we’ll check the possibility of building new functions with raw bytes in runtime.
