    A List to Popular Python Frameworks

    August 11, 2018 2
    A List to Popular Python Frameworks
    Python programming language is being popular for quite a few years and so does its frameworks. If you are new to Python programming language then I would recommend you to first learn Python Programming language. The reason behind Python popularity is its large number of frameworks, Python has a power to interact with almost every type of development platform either it is web, core development, database, data science, machine learning etc and there are much more to come. When it comes to languages and frameworks used for web development, ASP.NET and PHP are a nearly large number of frameworks available on the web such as Wordpress, Joomla, and other open source web applications built on PHP. But nowadays ASP.NET and PHP are not the daddies anymore because we have a wide variety of Python frameworks.




    A Python framework is a platform for developing software applications. It provides a foundation for programmers to build programs for a specific platform. A framework may include predefined classes and functions that can be used to process input, manage hardware devices, and interact with system software. But a perfect choice of frameworks depends upon the programmer's needs, skill levels and preferences.



    As a web developer, you would like a framework that enables you to rapidly develop and deploy applications. When it comes to a web application, there is always more to do than just coding your application. You need to understand the server side architecture and then there will be your application running on a Javascript enabled browser. Python has a wide range of frameworks, from cross-platform frameworks to platform-specific frameworks. In this post, we are going to discuss some of the best and widely used Python frameworks. Here, we are going to cover the top 5 most used frameworks of Python programming language.

    • Django
    • Pyramid
    • Web2py
    • Flask
    • CherryPy

    Django




    Django comes first in the list whenever we talked about Python frameworks. Django is a free open-source full stack Python framework that encourages fast growth and robust development. If you want to use your web app framework as CMS, Django probably be the good choice to go along with it. Django applications are based on MVT (Model View Template) design pattern which is similar to MVC. Django Framework uses ORM (Object Relational Mapper) to map its objects to database tables, which maps objects to queries, tables and records. The same concepts works with different databases resulting in the portability between databases types easier.  


    Advantages of Django framework

    • Django ORM is so complete and powerful that process optimization becomes easy.
    • The Rest framework collection of Django is easy and we can develop applications without any restrictions.
    • The GUI for Django makes it popular Python framework among all, using GUI we can design applications seamlessly.

    Pyramid



    Pyramid is an open source web application framework based on Python. Pyramid is rooted in two other products by Python: Pylons and repoze.bfg which are no longer developed. The legacy left by its predecessors caused Pyramid into a stable project. Pyramid was released in same year as Django (2005). Unlike Django, Pyramid framework is easy to customize and allows you to  create applications in a simple and sleek way. It does not force the programmer to use framework's phrases rather it allows programmers to code with an edge with high flexibility on standard projects. Some of the major Pyramid features are:
    • URL Generation
    • Extensible Configuration
    • Flexible authentication and much more.

    Advantages of Pyramid Framework

    • Pyramid framework is very useful for creating small applications quickly.
    • Pyramid is best for developers working on API projects, Prototyping a concept & Developing large web applications, such as a CMS.
    • Easy integration of databases like NoSQL, MongoDB and CouchDB.

    Web2py



    Web2py Python Framework was originally designed as a tools for students so that they can learn design, development and deployment at same platform. Web2py is a full stack Python framework developed in 2007 by a Computer Science Professor Massimo Di Pierro. Web2py is used for rapid development of fast, scalable, secure and portable database-driven web-based applications. Web2py is written and programmed in Python, though it comes with own web-based IDE which includes features like code editor, debugger and one-click deployment.

    Some of the bundled features of Web2py are amazing, since the are not present in other frameworks like:
    • two-factor authentication
    • helps creating javascript enabled websies with jQuery and Ajax
    • sending SMS messages

    Advantages of Web2py

    • One of the most appealing feature is web2py have high qulaity documentation.
    • Web2py comes with the web based IDE with full support. 
    • Web2py is backward compatible. A site one makes two version old, needs to be updated.
    Note: Web2py is quite popular Python framework but it is still not compatible with Python 3. Currently it supports Python 2.7, and there is no Python 3.X support.

Python is simple and easy to learn and it is highly readable moreover, it provides lots of high-level data structures. Python becomes quite popular due to its extensive application development support. Python allowed creating websites with a backend, data analysis with panda modules, GUI tools PyQt/Tkinter, predicting stock exchange using machine learning and game development using PyGame.



    Python is a multipurpose language because it can be used with a web, enterprise and 3D CAD etc. We don't need to use data types to declare variables because Python is dynamically typed language which means we can write a=5 to assign an integer value in an integer variable.

    History
    Python was developed by Dutch programmer, Guido Van Rossum in late 1980s. The implementation of Python was started in 1989 at National Research Institute for Mathematics and Computer Science in Netherlands. He originally wanted to create an interpreter, Guido initially thought the Unix/C hackers to be the target users of his project. Python is derived from many other programming languages including ABC, Modula-3, C, C++, Algol-68, SmallTalk, Unix shell, and other scripting languages.

    In 1994, Python 1.0 was released with new features like lambda, map, filter and reduce. Python 2.0 added new features like list comprehensions, garbage collection systems. On December 3, 2008, Python 3.0 (also called ""Py3K") was released. It was designed to rectify the fundamental flaw of the language.

    Python Versions over the Year
    There are various versions of Python programming language and it's being updated regularly with new features and support. The list of Python version with date of release is shown as
