Python Exercices

300+ Python exercises with solutions, organized by topic — written while learning Python, from the basics to more advanced data structures and algorithms.

Each folder contains exercises and their corrected solutions (corrigés), so you can attempt a problem first and then check your approach against a working answer.

🐍 Learning Python or brushing up before an interview? You're in the right place — browse a topic below, and if this saves you time, a ⭐ on this repo helps others find it too.

Why this repo might be useful to you

• Learning Python on your own — practice topic by topic, with a solution to check yourself against instead of guessing if your code is "right."
• Preparing for technical interviews — folders like recursion, sort_search, linkedList, and heap_q cover classic interview topics.
• Teaching or tutoring — a ready-made bank of exercises you can reuse or adapt for a class, workshop, or coding club.
• Quick reference — need a concrete example on JSON parsing, re (regex), or file_input_output? Find a working snippet instead of searching from scratch.
