Path Parameters in FastAPI
Learn about path parameters and automatic parsing of path parameters.
We'll cover the following
Introduction to path parameters
Path parameters help to call an API specifically to a particular resource or route. As we’ll specifically route to a particular resource, we don’t need to build a body that will be sent with the request to find a particular resource which reduces the execution time of the request.
Path parameters are surrounded by curly brackets and help the developers to control the representation of a particular resource in your application.
A path parameter is a string that appears before a query string and is within the path of an end-point. It provides an efficient way to parameterize a resource.
In FastAPI, we can declare path parameters with the same syntax used by Python format strings. Let’s look at the code below to see this concept in action.
