This repository documents a mission to build 100 practical Python projects using FastAPI or CLI.
But this is not a random list of coding exercises.
The projects are intentionally structured into three layers:
- 60 Small / Medium Projects → build core programming skills
- 13 Mega Projects → one large system per category
- 3 Capstone Projects → large multi-domain applications
This structure transforms the repository from a collection of exercises into a progressive engineering curriculum.
IMPORTANT 🚨: if you just want to practice python no fastapi or web integration, just see the sample.py of every project. also check the sample_fancy.py for in terminal good ui with color.
| Layer | Count | Purpose |
|---|---|---|
| Small / Medium Projects | 60 | Core algorithmic and backend practice |
| Mega Projects | 13 | Category-level system design |
| Capstone Projects | 3 | Large real-world applications |
| Total | 100 | Full development journey |
