## What it is
The source code and course materials for Python for Everybody (py4e.com), a free open online course and textbook for learning Python 3. It includes the book text, code examples, slides, and an autograding site built on the Tsugi LMS framework with LTI support.

## Use cases
- learn python from scratch for free
- find a beginner python textbook
- self-host a python course site with autograded assignments
- reuse open course materials in my own LMS via LTI
- translate a python course into another language
- get exercises and code samples for teaching python

## When to choose
- you want free, Creative Commons-licensed materials for teaching or learning Python
- you need autograded Python assignments integrated with an LMS
- you want to remix or translate an entire open course

## When to avoid
- you need an advanced or production-grade Python codebase - this is course content, not a library
- you want a polished turnkey product without self-hosting setup
- you need a permissively licensed codebase - the code has no explicit license

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, developer-tools
- domain: education, programming-languages, tutorials
- platform: self-hosted, python
- tags: python-course, open-educational-resources, mooc, lti, autograders, textbook, tsugi, web-server
