Projects and Applications in Python Web Development

Key Projects

• Personal Blogging Platform: Create a web application where users can write, edit, and delete blog posts. This project can be developed using Django, leveraging its ORM for handling blog post data.
• Online Portfolio: Develop a portfolio website that showcases your projects and skills. Use Flask for its simplicity and flexibility, allowing you to use custom templates easily.
• E-commerce Store: Build an e-commerce website where users can browse products, add them to a cart, and complete their purchases. This can be done using Django for its robust features suitable for complex applications.
• RESTful API Service: Create a RESTful API to expose your web application’s data to other applications. Flask or Django REST framework can be utilized for this purpose, enabling JSON responses and integration with front-end applications.

Python Code Examples

Example: Personal Blogging Platform using Django

            
            # models.py in Django
            from django.db import models

            class BlogPost(models.Model):
                title = models.CharField(max_length=100)
                content = models.TextField()
                created_at = models.DateTimeField(auto_now_add=True)

                def __str__(self):
                    return self.title
            
        

Example: Simple API using Flask

            
            from flask import Flask, jsonify

            app = Flask(__name__)

            @app.route('/api/posts', methods=['GET'])
            def get_posts():
                posts = [
                    {'id': 1, 'title': 'First Post', 'content': 'This is my first blog post.'},
                    {'id': 2, 'title': 'Second Post', 'content': 'This is my second blog post.'}
                ]
                return jsonify(posts)

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