Bytecode and .pyc files (sps25)

from Chaos Computer Club - archive feed (high quality) Hosted by Konrad Gawda

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. about this event: https://talks.python-summit.ch/sps25/talk/9NWPB9/
