                from django.db import models
                
                class BlogPost(models.Model):
                    title = models.CharField(max_length=200)
                    content = models.TextField()
                    created_at = models.DateTimeField(auto_now_add=True)

                    def __str__(self):
                        return self.title
            
        

RESTful API Service using Flask

            
                from flask import Flask, jsonify, request

                app = Flask(__name__)

                tasks = []

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

                @app.route('/tasks', methods=['POST'])
                def add_task():
                    task = request.json
                    tasks.append(task)
                    return jsonify(task), 201

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