• Personal Portfolio Website: Build a personal portfolio to showcase projects using Flask or Django, highlighting your skills and experience.

Python Code Examples

Blog Application Example (Django)

            
                from django.db import models

                class Post(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 Example (Flask)

            
                from flask import Flask, jsonify, request

                app = Flask(__name__)

                products = []

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

                @app.route('/products', methods=['POST'])
                def add_product():
                    product = request.json
                    products.append(product)
                    return jsonify(product), 201

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