About Inside The Python Virtual Machine
Inside The Python Virtual Machine is a detailed book that describes the CPython virtual machine and how it executes Python code. It covers the full pipeline from compiling Python source code through bytecode execution, including Python objects, code objects, frame objects, interpreter and thread states, the evaluation loop (ceval.c), the block stack, and generators. The book consists of 13 chapters, starting with an introduction and a high-level overview, then diving into the internals of CPython.
