python-world/python-mini-projects ? reverse-engineered prompt

Build me a small Python mini project that fits this repo and is useful for beginners.

I want a simple, self contained script that solves a real everyday task, with clear input and output, and a short README that explains what it does, how to run it, and a couple of examples. Keep it beginner friendly and easy to read, since this repository is for learning Python through small projects.

Please make sure the code is organized neatly in its own folder under projects, and include any basic setup notes if it needs extra libraries. If it helps, you can look up current docs online while building it. Also add a few sensible edge case checks so it does not break on bad input.
