Projects and Applications in Python Web Development

Key Projects

• Blog Platform: Create a blogging website where users can register, publish articles, and comment on posts. This project will utilize a backend framework like Django for the administration interface.
• Task Management App: Develop a simple task manager application allowing users to create, update, and delete tasks. Flask can be used to build a lightweight API for this app.
• E-commerce Website: Build a fully functional e-commerce site with features such as product listings, shopping carts, and user authentication. Django is ideal for such comprehensive projects.

Python Code Examples

Blog Platform 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
            
        

Task Management App Example (Flask)

            
                from flask import Flask, request, jsonify
                
                app = Flask(__name__)
                tasks = []
                
                @app.route('/tasks', methods=['POST'])
                def create_task():
                    task = request.json
                    tasks.append(task)
                    return jsonify(task), 201
                
                if __name__ == '__main__':
                    app.run(debug=True)
