200 Python Practice Problems

Stop Googling "Python practice problems" and solving random questions that teach you nothing.

This isn't another list scraped from the internet. It's a curated practice tracker with 200 hand-picked problems across LeetCode, HackerRank, Codewars, Exercism, CodeChef, and AtCoder — organized in a learning progression that actually builds your skills.

WHAT'S INSIDE:

3 difficulty tabs:

→ Easy (69 problems) — String manipulation, dictionaries, sets, two pointers, basic recursion

→ Medium (71 problems) — Sliding window, stacks, binary search, linked lists, DP, trees, graphs

→ Hard (60 problems) — Advanced DP, graph algorithms, backtracking, monotonic stacks, game theory

Each problem includes:

- Platform + direct link (one click to start solving)

- Python concept and topic tags

- "What You'll Practice" — so you know exactly what each problem teaches

- Estimated time

- Prerequisites — what to know before attempting

- Status tracker (Not Started / In Progress / Solved)

- Notes column for your own observations

WHY THIS SHEET WORKS:

✓ Problems are sorted in learning order, not randomly — each one builds on the last

✓ Difficulty is curated, not copy-pasted from platform labels — Easy means real problem-solving, not Hello World

✓ Every single URL is verified and working

✓ Platform color-coding so you can visually scan your progress

✓ Frozen headers + filters — works perfectly in Google Sheets

✓ Drop-down status tracker — track your progress without typing

Built by a senior data engineer with 6+ years of Python in production (BITS Pilani M.Tech). These are the problems I'd give someone who actually wants to get good at Python not just pass a tutorial.
