            from .models import Post
            
            def blog_view(request):
                posts = Post.objects.all()
                return render(request, 'blog.html', {'posts': posts})

Personal Portfolio Website with Flask

        
            # Simple Flask application
            from flask import Flask, render_template
            
            app = Flask(__name__)
            
            @app.route('/')
            def home():
                return render_template('index.html')
            
            if __name__ == '__main__':
                app.run(debug=True)

Task Management App with Pyramid

        
            # Simple Pyramid application
            from pyramid.config import Configurator
            from pyramid.response import Response
            
            def task_view(request):
                return Response('Task Management App')
            
            if __name__ == '__main__':
                with Configurator() as config:
                    config.add_route('tasks', '/tasks')
                    config.add_view(task_view, route_name='tasks')
                    app = config.make_wsgi_app()
