## What it is
A collection of 120+ interactive, test-driven Python coding challenges focused on algorithms and data structures for coding interviews. Each challenge includes Jupyter notebooks with constraints, test cases, reference solutions, Big-O analysis, and accompanying Anki flashcards.

## Use cases
- prepare for python coding interviews
- practice algorithm and data structure problems
- learn big-o time and space complexity
- drill coding concepts with anki flashcards
- find test-driven reference implementations of data structures
- practice competitive programming problems in python

## When to choose
- you are preparing for coding interviews in Python
- you want interactive notebooks with unit tests to validate your solutions
- you want reference solutions with complexity analysis
- you want spaced-repetition flashcards alongside practice problems

## When to avoid
- you need interview prep in a language other than Python
- you are looking for system design or object-oriented design practice (see the sister repo)
- you want a judged competitive-programming platform with leaderboards

## Facets
- artifact type: learning-resource
- maturity: stable
- function: testing, developer-tools
- domain: education, programming-languages, tutorials
- platform: python, cross-platform
- tags: coding-interview, interview-preparation, data-structures, algorithms, jupyter-notebooks, anki-flashcards, competitive-programming, practice-problems
