## What it is
A collection of notes and blog posts explaining the internals of the CPython interpreter, based on version 3.8.0a0. It covers built-in objects, modules, the interpreter core (GIL, GC, memory management), and C extension writing.

## Use cases
- understand how cpython implements dict and list internally
- learn how the gil and garbage collection work in python
- study cpython source code with guided notes
- learn how python import and attribute access work
- write c extensions for python
- understand python memory management internals

## When to choose
- you already know python and want deep interpreter internals
- you prefer illustrated source-code walkthroughs over formal docs
- you want to learn cpython object model, gc, or gil

## When to avoid
- you are a python beginner needing tutorials
- you need docs for the latest cpython version
- you want official reference documentation

## Facets
- artifact type: learning-resource
- maturity: active
- function: interpreter, documentation
- domain: programming-languages, tutorials, developer-tools
- platform: python, cpp, cross-platform
- tags: cpython-internals, python-internals, source-code-notes, interpreter-internals
