In this article we are going to introduce Python Web Development Frameworks ,

so as you know Python is general purpose language, it means that there are different

sections that you can use Python, one of them is Web Development, in this article we

are going to introduce the most powerful and popular Python Web Development Frameworks.

Python Top 5 Game Libraries

Python GUI Development Libraries

What is Framework ?

A framework is nothing but it is a collection of modules that make development easier.

They are grouped together, and allows us to create applications or websites from an existing

source, instead of from scratch.

1: Django

Django is a high-level Python Web framework that encourages rapid development

and clean, pragmatic design. and django is suitable for both front-end and back-end.

And also django is famous because of it is admin panel , and auto generated back-end

that allows you to manage completely your website.

There are different websites that are using Django, for example Instagram uses

Django as their back-end, also there are some more websites like Reddit, Spotify ,

Dropbox that are using Django.

Installation

You can simply install django using pip

pip install django

1	pip install django

For creating of Django Project you can use this command.

django-admin startproject MyProject

1	django-admin startproject MyProject

Now run your Project

python manage.py runserver

1	python manage.py runserver

This will be the result

2: Flask

Flask is a micro web framework that is written In python. We are saying micro framework,

but it does not mean that you can not build large applications with flask, it means that flask

provides a solid core with the basics services. But you can use extensions for the rest of the

work. For example in flask there is no native support for database, webforms, authentications

and many more but you can use extensions for this, for example for working with the forms

you can use flask-wtf or for working orm model you can use sqlalchemy. bong

Installation

You can use pip for the installation

pip install flask

1	pip install flask

Creating an example in Flask

from flask import Flask



app = Flask(__name__)



@app.route('/')
def index():
    return "<h1>Geekscoders.com - Flask Web Development</h1>"



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

from flask import Flask

app = Flask(__name__)

@app.route('/')

def index():

return "<h1>Geekscoders.com - Flask Web Development</h1>"

if __name__ == "__main__":

app.run(debug=True)

Run the example and this is the result

3: CherryPy

Cherrypy is a pythonic, object oriented web framework, CherryPy allows developers to

build web applications in much the same way they would build any other object-oriented

Python program. This results in smaller source code developed in less time. And also .

CherryPy is now more than ten years old and it is has proven to be very fast and stable .

cherrypy is being used in production by many sites. According to their documentation

CherryPy is used by Netflix . so Netflix uses CherryPy as a building block in their

infrastructure: “Restful APIs to large applications with requests.

Installation

You can install cherrypy using pip

pip install cherrypy

1	pip install cherrypy

Creating an example in CherryPy

import cherrypy


class MyApp():
    @cherrypy.expose
    def index(self):
        return "<h1>Geekscoders.com - CherryPy Example</h1>"




cherrypy.quickstart(MyApp())

import cherrypy

class MyApp():

@cherrypy.expose

def index(self):

return "<h1>Geekscoders.com - CherryPy Example</h1>"

cherrypy.quickstart(MyApp())

Run the code and this is the result

4: Bottle

Bottle is a fast, simple and lightweight WSGI micro web-framework for Python.

It is distributed as a single file module and has no dependencies other than the

Python Standard Library.

Installation

You can install bottle using pip

pip install bottle

1	pip install bottle

Creating example in Bottle Python Web Development Frameworks

from bottle import route, run



@route('/')
def Index():
    return "<h1>Geekscoders.com - Bottle Example<h1>"




run(host='localhost', port=5050, debug=True)

from bottle import route, run

@route('/')

def Index():

return "<h1>Geekscoders.com - Bottle Example<h1>"

run(host='localhost', port=5050, debug=True)

Run the code and this will be the result.

5: Pyramid

Pyramid is also an open-source Python-based web development framework. Its main

goal is to do as much as possible with minimum complexity. If you look at Megaframeworks,

make decisions for you, but if you don’t fit their viewpoint, you end up struggling with their

choices. On the other hand, Microframeworks force no decisions, making it easy to start.

But as your application grows, you’re on your own. The most striking feature of the

Pyramid is its ability to work well with both small and large applications.

Installation

pip install pyramid

1	pip install pyramid

Creating an example in Pyramid Web Framework

from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.response import Response


def hello_world(request):
    return Response('<h1>Geekscoders.com - Pyramid Example</h1>')


if __name__ == '__main__':
    with Configurator() as config:
        config.add_route('hello', '/')
        config.add_view(hello_world, route_name='hello')
        app = config.make_wsgi_app()
    server = make_server('localhost', 8080, app)
    server.serve_forever()
