Python Code Examples

Personal Blog with Flask

        
from flask import Flask, render_template, request, redirect

app = Flask(__name__)

@app.route('/')
def home():
    return render_template('home.html')

@app.route('/post', methods=['POST'])
def post():
    # Logic to handle post submission
    return redirect('/')

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

Task Management with Django

        
from django.http import HttpResponse
from django.shortcuts import render

def task_list(request):
    # Logic to retrieve tasks from the database
    return render(request, 'task_list.html', {'tasks': tasks})
        
    

Real-time Chat with Tornado

        
import tornado.ioloop
import tornado.web
import tornado.websocket

clients = []

class ChatSocket(tornado.websocket.WebSocketHandler):
    def open(self):
        clients.append(self)

    def on_message(self, message):
        for client in clients:
            client.write_message(message)

    def on_close(self):
        clients.remove(self)

app = tornado.web.Application([(r'/chat', ChatSocket)])
app.listen(8888)
tornado.ioloop.IOLoop.current().start()
