Python Beginner Exercises 🏋️🐍

Small, runnable practice exercises for new Python programmers — each with a built-in self-check and a worked solution.

These exercises mirror the learning track on pythonbeginner.help. Read a topic, then practice it here.

How to use

1. Make sure you have Python installed (3.8+).

2. Open an exercise in the exercises/ folder and complete the TODOs.

3. Run it — each file checks your answer with assert and prints ✅ when it passes:

   python exercises/01_variables.py

4. Stuck? Compare with the matching file in solutions/.

5. Run every exercise at once with the bundled runner:

   python run_all.py            # stop on first failure
   python run_all.py --keep     # run them all, report each result

The runner also reports any unfinished exercise (one that still contains ... TODO placeholders) as SKIP so you can see at a glance what's left to do.

CI

Every push and pull request runs all of the solutions/*.py files through GitHub Actions on Python 3.11, so the answers are always verified to work. See .github/workflows/exercises.yml.

Run all exercises at once

for f in exercises/*.py; do echo "== $f =="; python "$f"; done

…or just use the runner above.
