Python Code Examples

1. Simple Flask Application

            
from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/hello', methods=['GET'])
def hello():
    return jsonify(message="Hello, World!")

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

2. Basic Django Blog Model

            
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
            
        

3. Pyramid Simple Route

            
from pyramid.config import Configurator
from pyramid.response import Response

def hello_world(request):
    return Response('Hello World!')

if __name__ == '__main__':
    with Configurator() as config:
        config.add_route('hello', '/hello')
        config.add_view(hello_world, route_name='hello')
        app = config.make_wsgi_app()
    from wsgiref.simple_server import make_server
    server = make_server('0.0.0.0', 6543, app)
    server.serve_forever()
