Python Code Examples

Flask Personal Blog Example

            
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)
            
        

Django Online Store Example

            
from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='home'),
    path('product//', views.product_detail, name='product_detail'),
]
            
        

Pyramid Task Management Example

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

def home(request):
    return Response('Welcome to the Task Manager!')

if __name__ == '__main__':
    with Configurator() as config:
        config.add_route('home', '/')
        config.add_view(home, route_name='home')
        app = config.make_wsgi_app()
    # run WSGI application
            
        

Bottle Weather App Example

            
from bottle import Bottle, run

app = Bottle()

@app.route('/weather')
def weather():
    return "Current Weather: Sunny"

run(app, host='localhost', port=8080)
