How about rewriting a Python project in Rust? You can start slowly by moving out a part of your python project to rust with pyo3 and writing a module in Rust that's called by python.

If you want to have some fun, you can start out with writing a small game in Godot.

Or learn how to create a deterministic developer environment using devenv. That means that regardless of on which machine or environment your open your project in, the dependencies will all be the right version and so will the tools (debugger, live reload, db, etc.).
