Python Web Development Projects and Applications

Key Projects

Online E-Commerce Store: Create a fully functional e-commerce site using Django. Implement features such as user authentication, product catalog, and a shopping cart.
Personal Blog Platform: Build a blogging platform with Flask where users can register, create, edit, and delete posts. Incorporate Markdown for post formatting.
RESTful API Development: Develop a RESTful API using Flask or Django REST Framework that supports CRUD operations. This can serve as a backend for mobile or web applications.
Social Media Dashboard: Create a dashboard using Django that aggregates various social media feeds. Users can authenticate and display their posts in one feed.

Python Code Examples

Example Code for Online E-Commerce Store

        
            from django.shortcuts import render
            from .models import Product
            
            def product_list(request):
                products = Product.objects.all()
                return render(request, 'product_list.html', {'products': products})

Example Code for Personal Blog Platform

        
            from flask import Flask, render_template
            app = Flask(__name__)

            @app.route("/")
            def home():
                return render_template("home.html")
                
            if __name__ == '__main__':
                app.run(debug=True)

Example Code for RESTful API Development

        
            from flask import Flask, jsonify, request
            app = Flask(__name__)

            data = []

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

Real-World Applications
