This Swagger for Python tutorial is the crash course you need to learn all of the most important parts of Swagger UI and the OpenAPI specification.


In this tutorial we start off by creating a simple REST API in Flask, but we don't waste a lot of time there. We then use the Swagger online editor to document the Python REST API.


Once the Swagger UI comes up in the browser, we then test our API to prove that everything works.From there? We add to the OpenAPI specification, we add more methods and we even use the OpenAPI Generator to take an API first approach to RESTful APIs and have Swagger create Python code for us.If you wanted to learn how Swagger for Python works, this tutorial is for you!
