The Most Important Python Frameworks in 2019

In recent years, the demand for Python development services has increased significantly. The language has risen to become one of the most important among web developers. In fact, the PYPL Popularity of Programming Language Index currently ranks it as the most popular with a 27.34% share in the market.

As a free, open-source language, Python provides developers with immediate access to extensive libraries, modules, and a dedicated support community. Its simple syntax makes it very readable, which improves developer productivity. It’s also at the forefront of emerging technologies like Artificial Intelligence, Data Science and the Internet of the Things.

Some of the most important Python frameworks in 2019 include:

• Flask

• Django

• CherryPy

• Pyramid

• TurboGears

• Web2Py

Let’s take a look at each of these frameworks in more detail:

Flask

Flask is a microframework based on the Werkzeug and Jinja 2 templates. It’s particularly well-suited to small-scale development projects and it provides a solid base for developing web apps.

According to the 2018 Python Developers Survey, Flask has become the most popular Python framework and is used by 47% of web developers. Developers typically use Flask for creating customized backend frameworks. It’s relatively light and provides a built-in development server, unit testing and debugger. It also provides support for Google App Engine.

According to GitHub, companies that use the Flask framework include LinkedIn, Pinterest, Netflix and AirBnB.

Django

Django is a high-level, open-source framework that enables developers to create applications quickly and effectively. It doesn’t require any subscription and has an extensive range of libraries, which reduces the amount of coding required.

The 2018 Python Developers Survey reports that Django is the second most popular Python framework and is used by 45% of web developers. It’s used by some of the largest companies in the world, including Instagram, Pinterest and Mozilla as it constantly evolves to meet with the latest development trends.

Some of its key features include URL routing, database schema migration implements, and Object Relational Mapping for database tables. The framework is typically used for web and app development and can achieve a wide variety of tasks like creating RSS feeds, implementing content services, and creating sitemaps.

It also provides good security and helps developers prevent common cybersecurity attacks like clickjacking, SQL injection and cross-site request forgery. It has a good user authentication system so that user accounts and passwords are managed securely.

CherryPy

CherryPy is an open-source, minimalist framework with its own multi-strung server. Because it uses the Object-Oriented paradigm, it increases productivity when building web applications.

Its features include a setup framework, a thread-pooled web server and module framework. CherryPy can run on multiple platforms and has in-built support for tasks like reporting and testing.

It provides an extensive range of plugins and offers a powerful configuration system. For some recent examples of a CherryPy website in action, take a look at artist portfolio platform Workbook and French recruitment software company Job Affinity.

Pyramid

Pyramid is an adaptable framework that makes real-world web application development predictable and efficient by working with various different templating systems. It has an extensive range of features including its ‘cookie cutter’, which renders projects with a transaction management system, and the ability to simplify code with predicates. The framework is lightweight and is valued by developers for its quality and ability to scale projects.

It’s well-suited to development projects that require validation and prototyping. It’s also commonly used for creating web applications to be used as CMSs.

Pyramid’s add-on system offers a variety of template options, databases and security features. It has a strong support community and extensive documentation is freely available. According to its official website, Pyramid is used by companies like Mozilla, Yelp and SurveyMonkey.

TurboGears

TurboGears is a free, full-stack framework designed to overcome the shortcomings of other widely-used frameworks, particularly in templating and routing.

It can be used alongside a range of libraries and toolkits like SQLAlchemy, WebOb and Genshi, which speeds up the development process.

It uses a Model-View-Controller (MVC) design, supports multiple databases and Object Relational Mappers (ORMs) like SQLObject and SQLAlchemy. TurboGears official website reports that the framework is used by companies like SourceForge and Amnesty International.

Web2Py

Web2py is a full-stack, cross-platform framework that supports all popular operating systems. It provides developers with easy access and doesn’t require installation or configuration.

It simplifies web application development by providing a web server, a web-based interface and an SQL database. It enables developers to build, test and deploy web apps through web browsers.

One of the principal features of Web2Py is its ticket system for tracking errors. It offers a number of in-built components for managing HTTP requests, sessions and cookies. It also provides a code editor and a debugger.

Overview

In summary, Flask provides a good base for developing web apps and is well-suited to small-scale projects. Django enables developers to create applications quickly with its extensive range of libraries, which reduces coding time. CherryPy uses the Object-Oriented paradigm, which increases developer productivity.

Pyramid works with different templating systems, which makes it a predictable yet adaptable framework. TurboGears helps developers work around the shortcomings of other frameworks and Web2py enables developers to build web apps through browsers.
