Python Code Examples
1. Personal Portfolio Website with Flask
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)
2. E-commerce Platform with Django
from django.db import models
class Product(models.Model):
name = models.CharField(max_length=100)
price = models.DecimalField(max_digits=10, decimal_places=2)
description = models.TextField()
def __str__(self):
return self.name
3. Blog Application with Pyramid
from pyramid.config import Configurator
from pyramid.response import Response
def homepage(request):
return Response("
Welcome to my blog!
")
if __name__ == '__main__':
with Configurator() as config:
config.add_route('home', '/')
config.add_view(homepage, route_name='home')
app = config.make_wsgi_app()
