What is a web application using python language?

Python is an object-oriented programming language combined with dynamic typing and dynamic binding that makes it the most preferred language by developers to create a web application. Simplicity, flexibility, robustness, easy to use, compatibility and speed of this programming language make it one of the top languages in development. Python is a popular language among developers due to its support of modules and packages, which lets developers reuse code. Python is an interpreted language. This means that it is not converted to computer-readable code before the program is run but at runtime.  It can be used to perform a variety of tasks including machine learning, databases, data analysis, cloud infrastructure, design, site reliability/testing, web scraping, security, mobile development, APIs, and more. In this article, the reasons why Python is preferred in web app development is explained.

In order to create a Python web application, the developers use Python code to define what content to be shown to a user and what actions to be taken. Python can be used to build server-side web applications so your user doesn’t need to install anything to use your application; if the user has a browser and an Internet connection, then everything else will be run online. While a web framework is not required to build web apps, it’s rare that developers would not use existing open-source libraries to speed up their progress in getting their application working. Python is not used in a web browser. The language executed in browsers such as Chrome, Firefox and Internet Explorer is JavaScript. Most Python developers write their web applications using a combination of Python and JavaScript. Python is executed on the server-side while JavaScript is downloaded to the client and run by the web browser.

What are python frameworks?

A framework is basically a bundle of packages and modules that provide certain functionality and can be selectively changed to create application-specific software. Python offers many frameworks from which to choose from, enabling developers to do more with fewer lines of code. Django is an open-source, Python framework that is known for building complex data-driven websites. The framework has templates, libraries, and APIs that helps in building scalable web-development projects. TurboGears is another web application development framework, consisting of Web Server Gateway Interface (WSGI) components such as SQLAlchemy, Repoze, WebOb, etc. Similar to Ruby on Rails (RoR) or Apache Struts, TurboGears is built around MVC architecture that helps in rapid web application development. Numpy- Numeric Python is another framework that helps in performing mathematical and logical operations on arrays. The library consists of multidimensional array of objects and a collection of routines for processing the arrays. Pandas is a BSD-licensed, open-source Python library that provides easy to use data structures and data analytics tools for Python programmers.  A pyramid is a finishing-focused framework with the ability to start small, allowing you to code a solid foundation for your solution, and then to scale it up as needed. It is similar to Django in its compatibility with small and large applications but sets itself apart from Django in its complexity. While Pyramid and Django share the same core philosophy, Flask goes in the other direction. If the end goal is something simple, manageable, and customizable, it is suggested that you always use Flask. Flask is a micro web framework that’s built-in with development server and support for unit testing. This Unicode based Python framework supports RESTFUL request dispatching and is extensively documented for programmers to get started. Web2py is also a Python cross-platform framework for web development comes with code editor, debugger, and deployment tools. CherryPy provides the Create, Retrieve, Update and Delete functionalities for applications and helps in managing the project from anywhere using the user’s browser. The framework can run on multiple HTTP servers, have flexible plugin system, and has built-in profiling, coverage, and testing support. Falcon is a micro-framework for developing small scale applications and backend. The Falcon web framework encourages the REST architectural style and is available with a number of add-ons, templates, and complementary packages to ease development.

The advantages of using Python

Python is easy to use. When you compare Python to some other programming languages, it might seem like Python was designed for beginners. However, that is not necessarily the truth. Of course, it is perfect for first-time developers but that doesn’t mean the advanced users don’t use Python for web development. One of the main advantages of Python is its reliance on whitespace and common expressions which allow you to do a lot more with a lot less code compared to, for example, C++ or Java.

Python web development quite simply because you can easily achieve more functions with fewer lines of code. Basically, if you know the basics, you could build a rudimentary game in 2 days no problem. With keeping the fact in mind that it takes fewer lines of the code when you need to build ideas and prototypes quickly, Python is definitely the way to go.

Debugging Python web app is easy because of the fact that there is no compilation step which makes the debug cycle extremely fast. While the majority of programming languages aren’t exactly forgiving of mistakes, that is not the case with Python. Python web development is easy not only because of its amazing readability but also because the code doesn’t break when minor mistakes occur.

As an open-source platform built by thousands of contributors from all corners of the world, Python is a crowdsourcing success story. It’s robust, scalable, well designed, and easy to learn, a product of several years of the best minds coming together to build a language with clearly-defined features. The fact that it has an open-source license also means Python can be implemented and modified in any way you please. It’s possible to insert blocks of other code to make the language even more feature-rich, all at no cost. You can also tap libraries to create applications for data analysis, language processing, and machine learning among many others.

python, language, applications

Python has been widely used for server-side programming, due to its dynamic website creation capabilities. This language is widely used for fast prototyping and building highly scalable web applications. Furthermore, these Python frameworks reduce the development effort through the provision of a variety of built-in functionalities. The only challenge would be which one to use, tailored to specific needs for better results.
