Python Web Development Frameworks

Full Stack Frameworks

It gives full support to developers including basic components like form generators, form validation, and template layouts etc

1. Django is a high-level Python Web application development framework that encourages us to develop things rapidly, It uses pragmatic design.  It’s free and open source.

2. Web2py is a free open source full-stack development framework in python which allows the user to develop things quickly. It is a cross-platform framework that supports all popular operating systems. 

3. TurboGears is a free, open source and data-driven full-stack web application development Python framework. With the help of Javascript developer tools, developers can simply the web application.

4. CubicWeb is a semantic, free and open-source Python web framework, that empowers developers to efficiently build web applications by reusing components and following the well known object-oriented design principles. 

Non Full Stack Frameworks

Non-full stack frameworks are also called as Micro frameworks because it doesn’t have many components like full stack frameworks.

1. Flask is a microframework for Python based on Werkzeug, and Jinja 2. The main purpose is to develop a strong web application base. As compared to Django, Flask is best suited for small and easy projects.

2. CherryPy is a Minimalist Python Web Framework. It uses the Object-Oriented paradigm to develop web applications. This approach helps developers to develop web applications within a short period of time.

3. 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. It is an easy-to-use lightweight framework generally used to build small web applications. It is mainly used to develop API’s.

4. Tornado is a python web framework with asynchronous network library. By using the non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user.

15. Scapy. A packet sniffer and analyzer for python made in python.

16. pywin32. A python library which provides some useful methods and classes for interacting with windows.

17. nltk. Natural Language Toolkit

18. nose. A testing framework for python.

19. SymPy. SymPy can do algebraic evaluation, differentiation, expansion, complex numbers, etc.

20. IPython. It has completion, history, shell capabilities, and a lot more.

Python program to renaming the file or directory

# X is the original name and Y is the name to be changed
import os, sys
print ("The dir is: %s"%os.listdir(os.getcwd()))
os.rename("X","Y")  
print ("Successfully renamed.")
print ("the dir is: %s" %os.listdir(os.getcwd()))

Top 5 Python Web Frameworks

1) Django

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.
Ridiculously fast + Reassuringly secure + Exceedingly scalable


TurboGears 2 is a reinvention of the TurboGears project to take advantage of new components, and to provide a fully customizable WSGI (Web Server Gateway Interface) stack. 


Free open source full-stack framework for rapid development of fast, scalable, secure and portable database-driven web-based applications. Written and programmable in Python

4) Flask

Flask is a Python framework available under the BSD license. It was inspired by the Sinatra Ruby framework. Flask depends on the Werkzeug WSGI toolkit and Jinja2template.

 5)Bottle

Bottle is a microframework. Originally meant for building APIs, Bottle implements everything in a single source file. It has no dependencies apart from the Python Standard Library. Coding with Bottle gets you closer to the metal than coding with any full-stack framework.
