In this webstory, we will learn how to build a REST API in Python. We will use the Flask framework, which is a popular Python framework for creating web applications.
Once Flask is installed, we can create a new Python file for our REST API. We will call this file api.py.
The next step is to define the routes for our REST API. A route is a URL that maps to a specific function in our API.
For example, the following code defines a route that returns all the users in our database:
The @app.route( ) decorator tells Flask that this function is a route. The /users part of the decorator is the URL that the route maps to. The get_users( ) function is the function that is called when this route is requested.
The jsonify( ) function converts the data in the users variable to JSON format. JSON is a standard format for exchanging data between computers.
The final step is to run our REST API. We can do this by running the following command in our terminal:
Our REST API is now running on our local computer. We can test it by opening a web browser and navigating to the URL
