Modern Python through FastAPI and friends - Dubai - AI Everything - Gitex

Explore some of the great features from modern Python and how to use them with FastAPI and friends.

We will see how to make code that is less error-prone, simpler, more efficient, and have a great developer experience, all at the same time.

And all this while including best practices by default.

We will see a bit about type annotations (type hints), async/await, and an overview of FastAPI, Typer, and others.
