Python Code Examples

Blog Application Example (Flask)

        
from flask import Flask, render_template, request, redirect, url_for

app = Flask(__name__)
posts = []

@app.route('/')
def index():
    return render_template('index.html', posts=posts)

@app.route('/post', methods=['POST'])
def create_post():
    post_title = request.form.get('title')
    post_content = request.form.get('content')
    posts.append({'title': post_title, 'content': post_content})
    return redirect(url_for('index'))

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

E-commerce Application Example (Django)

        
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})

Real-time Chat Application Example (Tornado)

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

class ChatWebSocket(tornado.websocket.WebSocketHandler):
    clients = []

    def open(self):
        ChatWebSocket.clients.append(self)

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

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

application = tornado.web.Application([
    (r'/chat', ChatWebSocket),
])

if __name__ == '__main__':
    application.listen(8888)
    tornado.ioloop.IOLoop.current().start()
