Typer Fun

What is this?

I've just discovered Typer, a library for building command-line interfaces (CLIs) in Python. It's built on top of Click and uses Python's type hints to provide a simple and intuitive way to create CLIs.

This is FastAPI sibling.

Why?

Instead of adding this to my bookmarks, I will just go ahead and create a repo for it. I will add more examples as I learn more about Typer.
