Notice the changes from a flask app, the @app.route is now @api.route as we are now using flask-restx the class HelloWorld has a parameter Resource (imported from flask-restx) and the function name is get (it will be post or put for a post, put request respectively). tags: Before we present other Flask strengths, lets talk about blueprints.
