what is python used for in web development
For those who are new to programming, they might be wondering where exactly can Python be used for web development?

Probably they already know that Python is currently the world leading programming language. It won its place by its simplicity and efficiency. With Python you can write programs with very little overhead, which is vital in development in general. The syntax looks so natural, the language is very capable, so these two lead to a programming language that is used even by big companies, like Google, Facebook, NASA, Netflix!…

But can we really use Python for web development?

The answer is definitely yes! Python fits the landscape due to it’s stated advantages, and its ability to write the server-side (back-end) even WITHOUT using a framework. Even though, it is unusual for someone to write an application not using a framework (Flask, Django, Pyramid, CherryPy, Tornado, Sanic), because the work is done easier and smoother if a framework is used. Several content management system (CMS) based on Python are also ready to be used to build website instantly.

Now that we know for sure that Python is a good way to develop back-end software solutions, let’s dive into it head first! Below we have the most usual frameworks explained.

Flask

An open source micro-framework built for Python. It is classified as a “micro-framework” because there is no database abstraction layer or form validation utility. These wouldn’t be needed anyway for someone who is just grasping the bottom level of web development using a programming language.

A beginner should start with Flask, because it’s designed with small project and prototypes in mind. A more complex project would require a more advanced framework, like Pyramid. Also, Flask is the most commonly used framework in web development with Python. Flask has a numerous community, so it is guaranteed to find the help you may be looking for when having difficulties.

Flask is suitable for beginner not only due to its simplicity, but also it is a good framework to start learning the web development in Python. You can extend your Python skills by writing simple web functionality with Flask.

Django

Now, it’s time for the secret weapon! Django is the complete framework even for corporate-level applications. It allows designing starting from database applications up to GPS and beyond. The philosophy it promotes is DRY (Don’t Repeat yourself).

The way you are supposed to build your project using this specific framework is through code reusability. Its modular way of arranging code is extremely modular; meaning you can attach or detach modules without any hassle.

Django is fully loaded with simple tools which enclose complex but commonly used processes. Subsequently, building web apps can be done pretty swiftly. However, a solid foundation of Python language and object-oriented programming is required in order to run those tools effectively.

Django uses the unique Object-Relational Mapping which leads to high compatibility with the common databases (MySQL, PostgreSQL, Oracle…) but you can use numerous databases at once. For reduction of page loading time, which are part of SEO (Search Engine Optimization), there are some interesting techniques Django uses, so your app is guaranteed to be boosted in the search engines’ charts.

When you ready to explore Django web framework, you can start learning from Django 2 Web Development Cookbook. You will not only build a variety of web apps, but you will also test, deploy, and scale your web applications efficiently.

Pyramid

A fully-fledged web framework, that would fit between the two reference points – Flask and Django. I would define it as just what an intermediate developer would search for. With Pyramid, you can start working on some deployable projects, as it offers the capability of starting with small
projects and grow them as much as needed.

Documentation regarding this framework is as comprehensible as it is powerful. Being a Professionally-designed framework, it comes with new utilities making the developer’s job easier: Templates, User-defined assets, Action coordination via events, session data storage and more.

Pyramid was a very popular web framework back in the day. However Flask and Django have gained much more popularity than other Python web frameworks these days. Nevertheless, there are still many corporations who use Pyramid and mastering this framework will give you so many advantages.

Sanic

You've probably heard micro-frameworks and full-stack framework before. Sanic is a different type of web framework, It's an asynchronous framework. Unlike traditional frameworks, asynchronous framework implement parallel programming which facilitates a unit of work to run independently from the main thread.

Sanic is designed for fast HTTP responses by using asynchronous event handlers available in Python 3.5 and up. It is developed with a syntax based on Flask framework and on top of uvloop, a Python wrapper for libuv.

The Sanic author's benchmark indicated that this framework capable of handling more than 33k request per second.

Nevertheless, Sanic is still in its infancy as a Python web framework. Sanic may become a full replacement of Flask as the future of microframework, or dissolved into Flask as it’s async core. Sanic's code library ecosystem has not been widely developed, that required you to build a many functions from scratch.

Another thing to consider, Sanic is not Windows friendly due to the dependency from uvloop. You must work on other OS to develop and deploy it.

But don't let these drawbacks discourage you, asynchronous programming is the next best thing in Python. Sooner or later, you are going to embrace it.

Django CMS 

CMS stands for Content Management System. Alike other tools like Wordpress and Joomla, Django CMS is a robust and easy tool to use. Front end editing is done simple and easy through the intuitive content management interface.

The main power of Django CMS is its lightweight core that is easy to implement. Integration with other popular applications can be done conveniently. It's not surprising that many international companies such asL’Oreal, National Geographic, and Parrot, have chosen Django CMS for their content management and delivery systems.

The django CMS is exceptionally user friendly, it has an intuitive drag and drop interface. New users of Django CMS won’t have any difficulties to understand. Django CMS is profoundly suitable for companies with international markets. It supports internationalization (i18n) which makes multi-lingual website can be built automatically.

It’s documentation is very detailed and cautiously written. The document can be edited using very powerful tools through simple interfaces. Django CMS benefits from a healthy, active community that writes efficient code, which is tested automatically.

What is Python Used for in Web Development
Mezzanine CMS

Mezzanine is another Content Management System based on the Django framework. This one is also a very powerful CMS for a somewhat more seasoned Web Developers. What recommends Mezzanine CMS is its wide range of action and customizability of the resulting app.

Some key features it includes are the ability to schedule a publishing, enables the owner of the application to manage accounts and send registration via e-mail verification. Also, integrated sharing tools using the common social media platforms.

URL shortening for easier sharing, Spam filtering, facile editing of visual elements are integrated within the core Mezzanine package. Popular third party packages can extend the abilities of Mezzanine even further! Captcha, Themes, Calendars and Podcasts can be integrated in the specific app through a few third-party libraries.

Mezzanine was designed mainly for blogger. It has much better setup for a blog than Django CMS. One feature that bloggers will fall in love to Mezzanine is the capability to import Wordpress. Most bloggers use Wordpress, and if you are ready for something new, you can learn how to import your Wordpress to Mezzanine in this blog post.

Another big plus for Mezzanine is its seamless integration with Django apps. If you know Django and able to built a unique app, you can effortlessly turn that app into a Mezzanine plugin.

Framework and CMS essentials

Python is currently leading in the computer and even web programming sectors. Many developers and companies turn to Python because of the advantages that Python offers.

Python is leading back-end technology because there are many frameworks under very active development. Using frameworks is vital, from some point up. Here we have shown you the most famous ones, when to use them, and their upsides.

Flask represents the perfect starting point for an upcoming web developer. It’s a micro-framework, It will improve your Python skills through hands-on coding experiences. For someone who just starts up, you learn a lot of things with Flask.

Django is a professional tool that should be used later in your career. If you opt to jump right in Django framework, you will need work harder to understand advanced concepts of Python web framework.

Pyramid should be adopted after you have done some basic apps, and you know your way around a framework. You are certainly free to skip this framework if you feel sufficient building website by using Flask or Django.

In contrast, Sanic represent the future of Python web framework. Asynchronous programming has become so popular in Python. You need to embrace it whenever you have an opportunity.

Django CMS and Mezzanine CMS are very good tools, which I recommend you start using after some experience with a framework like Django. This way you know how to troubleshoot and make an efficient app.

Content Management Systems are a great way of creating very ambitious projects, that for example, include form validation and CAPTCHA code, newsletters and so on.
