Top Python Frameworks and Libraries that will elevate your work

Introduction about Python

Python is a general-purpose programming language widely used in everything from creating banal web pages to controlling rovers on other planets.

The scripting language is universal and is the most popular programming language in the world (according to the Tiobe edition, which compiles the top of the most popular languages).

It’s easy to start with Python, it can build large and complex systems, and it has a wealth of libraries to do just about anything.

Any software product, regardless of complexity and specifics, can be created in Python and one of the hundreds of frameworks developed.

Third-party libraries like Pyromid, Flask, Django, and dozens of others are used to create web applications and sites to help replace PHP and JavaScript.

Even full-fledged data management systems are written in Python, which later becomes analogs of mastodons like WordPress and Drupal. Also, Python is used to create auxiliary tools for working with the web, such as scrappers that collect information from other people’s web pages.

Powerful applications and frameworks have been built in Python, such as the GIMP image editor, the Ubuntu app store, 3D graphics editors, BitTorrent networks, etc. The list can be continued for a long time.

Also, Python often becomes an integral part of such applications. For example, Sublime Text is written in C++, while its extensions and plugins are written in Python.

Apps for iOS and Android are built in hundreds of different languages, and Python is one of them. More often, of course, this concerns their server component because more common frameworks or some highly specialized technologies are responsible for the interface. Nevertheless, Python is often responsible for the backend (that is, the program’s internal logic).

Python is used in game development precisely because of its ability to create reliable and well-thought-out scripts using the language. They are responsible for the movement of characters, the performance of any actions, the transition from one event in the game to another, and so on.

Like many other languages, Python has a package manager called pip. It allows you to quickly, or instead in one command, download any of all available libraries and frameworks. There are more than 300 thousand in python, and the daily download is several tens of millions.

However, among the many, some are used more than others, are very popular, perform important functions for the programmer, and supply very cool tools that hundreds of thousands of programmers worldwide use daily.

Python Frameworks

There are many Python frameworks available. Which one you choose will depend on your specific needs and preferences. Some popular ones include:


Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It is an open-source framework that allows developers to create web applications of almost any level. It is among the best Python frameworks and deservedly popular.

Django has a huge set of additional libraries and support from a huge community of developers, which significantly simplifies and speeds up development.

Key features of Django:

  1. the presence of its ORM (from the English. Object-Relational Mapping, “object-relational mapping”);
  2. the built-in administrative interface (in simple terms – admin panel);
  3. template engine;
  4. form library;
  5. caching and internalization system;
  6. authorization and authentication system.


Flask is a lightweight Python web framework that provides useful tools and features for creating web applications.

The Flask framework has a small source codebase, which is why it is called a microframework. But this does not mean that it has fewer features than the same Django. By default, it only includes a request handler and templating engine, and the simplest Flask application might be just a few lines long. The developers of this framework consciously wanted to keep the core simple but extensible.

Nevertheless, with the help of Flask, you can implement almost any task: from a simple one-page site to a serious project with authorization, authentication, and other features. Flask is suitable for tasks that require flexibility in the choice of components. The developer himself decides what is useful to him in his work.

Is Flask at the heart of such large services? like Reddit, Netflix, Pinterest, Twilio, and taxi aggregator Lyft.

Key features of Flask:

  1. built-in development server and debugger;
  2. request dispatching in RESTful style;
  3. built-in support for unit testing;
  4. using the Jinja2 template engine;
  5. 100% WSGI 1.0 compatible;
  6. Lots of community-provided extensions.


Pyramid is a flexible Python web framework suitable for small and large applications. The growing popularity of the Pyramid framework is universal. It can be used for projects of any level of complexity. It has earned high marks in the Python developer community for its transparency and proven reliability. Tech giants like Mozilla, Yelp, Dropbox, and SurveyMonkey use it.

Megaframeworks tend to make decisions for the developer regarding the architecture of the application or the choice of specific components, such as ORM. But if your needs don’t match their point of view, you will end up fighting their choice.

Microframeworks, on the contrary, do not impose any solutions, which sometimes play into your hands. However, when your application grows and needs new components, you are left with a choice in the matter of choice.

In both cases, the focus is on getting started on the project: either too much or too little. Pyramid is the golden mean. This framework can be a micro-framework at the very beginning of the project, and as it grows, it will provide everything you need at every stage to bring the project to a successful completion.

Pyramid key features:

  1. the ability to write an application in one file;
  2. serving requests for static files;
  3. toolbar for debugging the application directly in the browser;

  1. a non-blocking web server that can scale to thousands of open connections;
  2. support for WebSockets and long-polling, allowing real-time communication between the server and clients;
  3. a simple template engine for rendering HTML and other content;
  4. support for third-party authentication and authorization (e.g., OAuth).


Web2py is a full-stack Python web framework that includes a web server, a database, and a web-based IDE.

The Web2py framework was originally conceived as a learning tool focused on usability and ease of use. For example, it lacks project configuration files. The framework’s architecture was developed by analogy with solutions such as Ruby on Rails and Django.

The whole process of development, debugging, testing, and administration of a remote database, can be organized without any third-party tools through its web interface, which is also a web2py application.

In addition, each application is provided with an auto-generated Django-like administration interface.

Key Features of Web2py:

  1. integrated web development environment;
  2. built-in components for all primary functions;
  3. mechanisms for authentication and access control by roles;
  4. jQuery support for Ajax and UI effects;
  5. support for internationalization;
  6. automatic error logging along with context.
