Explore the intricacies of Python bytecode in this comprehensive EuroPython 2013 conference talk. Delve into the fundamentals of bytecode, its usage, and the importance of studying it. Gain insights into opcodes, the virtual machine, stack operations, and variable types. Learn about free and cell variables, data and metadata, and how to create a simple disassembler. Discover advanced topics such as function defaults, globals, const tables, and line numbers. Examine how modules and classes function as callables, and understand the process of creating functions by hand. Compare readable and hand-coded bytecode, and explore class disassembly techniques. Conclude with an overview of the simplest possible virtual machine and valuable resources for further study.
