In 2025, all you need to take a #Python application from a simple script to production is: uv. But, how do you setup your project directory structure for success? How do take advantage of the latest development in Python packaging tooling like dependency groups? I'll walk you step-by-step to my proven project layout that we use for our vital production applications. We start with a simple FastAPI view and we end up with a nice local project that's fun to work on and that's easy to give to other people.
