Python Code Examples
Personal Blog using Django
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
REST API with Flask
from flask import Flask, jsonify, request
app = Flask(__name__)
tasks = []
@app.route('/tasks', methods=['GET', 'POST'])
def manage_tasks():
if request.method == 'POST':
task = request.json
tasks.append(task)
return jsonify(task), 201
return jsonify(tasks)
if __name__ == '__main__':
app.run(debug=True)
Real-time Chat Application using Tornado
import tornado.ioloop
import tornado.web
import tornado.websocket
class ChatSocket(tornado.websocket.WebSocketHandler):
clients = set()
def open(self):
self.clients.add(self)
def on_message(self, message):
for client in self.clients:
client.write_message(message)
def on_close(self):
self.clients.remove(self)
app = tornado.web.Application([(r'/chat', ChatSocket)])
app.listen(8888)
tornado.ioloop.IOLoop.current().start()
