7 Top Python Frameworks You Should Consider for Your Next Project

In today’s tech era, Python development is climbing new heights of popularity and has become one of the world’s most popular programming languages.

According to Tiobe’s Programming Community Index for May 2021, Python is steadily increasing in popularity and remains on the second position as the most popular programming language.

Python is an advanced, interpreted programming language with an easy-to-use syntax and robust libraries that makes it stand out among other web development languages.

If you are developing any Python-based web apps, you should choose any of the most popular Python frameworks to code as it puts a major emphasis on Python for web application development.

What is Python used for? Python is a simple, versatile language that fits all areas such as building a web app, DevOps, and data structures.

It is also a top choice for data scientists, researchers looking into new technologies such as Machine Learning, Big Data, Artificial Intelligence and data mining.

Companies that use python such as Netflix, Instagram, Dropbox, are relying on Python as they have a high loading website that processes millions of user requests per day and Python helps them sustain their top-notch performance.  Python is also employed by the infrastructure team at Facebook. 

To make the most of these Python web frameworks, you must consider a Python web application framework that provides a clear code structure to developers throughout the planning, cross site scripting, SQL injection flaws, file execution, and MVC designing process.

What Are Python Frameworks?

Python web frameworks are a collection of modules or packages which help developers in writing a web application in the Python programming language.

When they choose Python for rapid development, they don’t have to worry about the use of low-level facts, like multiple protocols, thread management, or sockets.

Frameworks automate the performance of basic solutions that provide developers the adaptability to concentrate on websites instead of the general routine processes.

The web frameworks give website developers, web designers, system administrators, and Linux operators the freedom to develop a structure by providing a default model for app structuring that is quick, consistent, and effortlessly maintainable.

These web frameworks also diminish the coding time and enable developers to be more focused due to the simultaneous command line (CL) processing and strong typing.

Python backend frameworks have a higher source order abstractions and metaprogramming potential to develop large and complicated code systems and have a variety of libraries for unique features.

Let’s observe a few of the operations involved in web app development that require usage of web frameworks for Python:

  • URL routing and data-driven manipulation
  • Input form validation
  • Output formats along with template engines
  • Database connection configuration
  • Data security against cross-site request forgery (CSRF)
  • Session storage and retrieval

Well, the selection of frameworks needs to be made by considering the basic requirements and preferences of the user. 

Types of Python Frameworks

Type of Python Frameworks

While talking about the availability of open-source Python frameworks, there are basically three types of frameworks – full-stack frameworks like Web2py and Pyramid, micro-framework like Dash and CherryPy, and asynchronous frameworks like Sanic and Growler. 

Let us have some views on these frameworks.

  1. Full Stack Framework

    Full stack are one of the best Python frameworks, known as one-stop-solution for fulfilling all kinds of app building requirements.  This approach has a lot of databases and components that are commonly included in the full-stack framework such as – form validation, form generators, and template layouts. 

    Here are some examples of full stack frameworks:

    • CubicWeb
    • Django
    • Web2Py
    • Giotto
    • Pylons Framework
    • Pyramid
    • TurboGears

    From the above list of full-stack Python frameworks, Web2py, an open-source framework, permits developers to create robust code by using the object-oriented pattern with the utmost ease. It is written in Python and is fabricated to diminish tiresome program agendas, such as building web-based visualization forms from the beginning. 

    One of them is CubicWeb that embeds Relational Query Language (RQL) with an aim to simplify any query related to the data. Let’s view each of them in detail and choose the best use cases.

    Whereas, Pyramid is a lightweight framework intended to turn trivial web technologies into huge one. Pyramid operations are carried on all versions of Python programming language.

    Pylons combine the best ideas from the ecospheres of Python, Perl, and Ruby, enabling an organized and flexible framework.

  2. Micro-framework

    These kinds of web frameworks are known as the lightweight framework (non full stack framework) because they do not offer additional patterns and functionalities compared to a full stack framework, such as multi-threaded database abstraction layer, form validation, specific tools, and libraries.

    The users who want to use this open-source Python web framework must put a lot of effort to form code, and need to add additional requirements and operations manually. Some of the best Python frameworks of this type are:

    • Bottle
    • CherryPy
    • Dash
    • Falcon
    • Flask
    • Hug
    • MorePath
    • Pycnic
  3. Asynchronous Framework

    Asynchronous web frameworks are now taking over its place as a microframeworks that allows a user to handle large sets of concurrent connections. 

    Characteristically, an asynchronous web framework is mainly built for Python which uses the asyncio networking library of programming languages.

    Sanic is a server web framework that allows developers to use async/await syntax which is included in Python 3.5. The aim of the Sanic assignment is to supply an easier way to function in a high-performing HTTP server that is simple to construct and scale and supports request handlers. 

    According to the benchmark test held by Sanic, Falcon’s capabilities of managing most of the requests with similar hardware is best as compared to all its contemporaries.

    • AIOHTTP
    • Growler
    • Sanic
    • Tornado

Things to Know Before You Choose The Right Web Framework

According to Stack Overflow, 66.7% of web developers prefer Python as their programming language for web development. Python is the top choice, fourth year in row, as the technology most developers want to use someday.

But there are certain things that companies need to consider before deciding which web development framework they should use.  First of all, it needs to look at the size and complexity of the coding strategy. 

If you are planning to develop a large structure filled with lots of requirements and features, a full-stack framework will be the right choice.  On the other hand, if it is planning a small and simple app product, you should think about microframeworks.

Secondly, you need to check if the framework you are choosing is up to the mark and perfectly fits your web project. This is an important step to remember while choosing the right framework for the projects that require running on several web servers, handling vast amounts of traffic, and supporting new additional features to excel code functionality.
