Path Parameters in FastAPI
Explore how to implement path parameters in FastAPI to target particular API resources without request bodies. Understand how FastAPI uses curly braces to define parameters, how these are passed to functions, and how to specify data types for automatic parsing, improving API efficiency and clarity.
We'll cover the following...
