## What it is
A collection of short but challenging Python programs and Jupyter notebooks by Peter Norvig, designed as practice material for perfecting programming skills. Topics range from writing a Lisp interpreter to probability puzzles and Project Euler problems.

## Use cases
- improve my python programming skills with challenging exercises
- learn how to write a lisp interpreter in python
- practice solving project euler problems
- study well-written python code from an expert
- find programming puzzles to sharpen algorithmic thinking
- learn probability and math concepts through python notebooks

## When to choose
- you want to treat programming as a craft to master through deliberate practice
- you prefer reading and running self-contained Jupyter notebooks
- you want expert-level examples of clean, idiomatic Python

## When to avoid
- you need production-ready software or a reusable library
- you want step-by-step beginner tutorials that hold your hand
- you need a structured curriculum with graded exercises

## Facets
- artifact type: learning-resource
- maturity: active
- function: interpreter, math, developer-tools
- domain: education, programming-languages, tutorials
- platform: python, cross-platform
- tags: jupyter-notebooks, programming-practice, peter-norvig, etudes, puzzles, algorithms
