How are REST API principles implemented when developing in Python?

REST API principles in Python development are implemented by adhering to REST architectural constraints:

• Using HTTP methods (GET, POST, PUT, DELETE) for resource operations.
• Identifying resources via URLs.
• Statelessness on the server.
• Using standard HTTP response codes.

Frameworks such as Flask or Django REST Framework are often used for implementation.

Example of a simple REST API in Flask:

from flask import Flask, jsonify, request

app = Flask(__name__)

items = []

@app.route('/items', methods=['GET'])
def get_items():
    return jsonify(items)

@app.route('/items', methods=['POST'])
def add_item():
    item = request.json
    items.append(item)
    return jsonify(item), 201

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

This approach provides a standardized and convenient interface for client interaction.
