Path Parameters in FastAPI

Introduction to path parameters

Path parameters help to scope the API call down to one single resource, thereby saving the trouble of having to build a body to deliver something as simple as a resource finder.

Path parameters are surrounded with curly brackets and offer a unique way for developers to control the representation of a specific resource.

Path parameters are placed before the query string and just within the path of an endpoint. They provide developers with an effective way to parameterize resources.

In FastAPI, we can declare path parameters with the same syntax used by Python format strings. Let us see the code below to understand the concept.
