Use Flask to define routes and handle HTTP methods (GET, POST, PUT, DELETE). Use Flask-RESTful for building APIs with less boilerplate code and better organization.

Implementing a RESTful API using Flask is a popular choice for Python developers due to its simplicity and flexibility. Start by installing Flask and Flask-RESTful, which provides tools for building REST APIs with minimal boilerplate code. Define your resources by creating classes that represent each endpoint. For example:

from flask import Flask
from flask_restful import Api, Resource

app = Flask(__name__)
api = Api(app)

class HelloWorld(Resource):
    def get(self):
        return {'hello': 'world'}

api.add_resource(HelloWorld, '/')

if __name__ == '__main__':
    app.run(debug=True)

In this example, a simple GET request to the root URL returns a JSON response. You can define additional methods for other HTTP verbs like POST, PUT, and DELETE within your resource classes. Utilize request parsing and validation features provided by Flask-RESTful to ensure that incoming data is properly formatted. For more complex APIs, consider implementing authentication and authorization mechanisms to protect your endpoints. By leveraging Flask and its extensions, you can build robust and scalable RESTful APIs efficiently.
