How can I create a RESTful API using Flask?

To create a RESTful API using Flask, you can use the Flask-RESTful extension. First, install it using pip.

What are the basic steps to set it up?

1. Install Flask and Flask-RESTful. 2. Create a Flask app. 3. Define resources and routes. 4. Run the app.

Can you show me a simple code example?

Sure! Here's a basic example:

from flask import Flask
from flask_restful import Resource, Api

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)

How do I test the API once it's running?

You can test the API using tools like Postman or curl. For example, use curl http://127.0.0.1:5000/ to see the response.
