Python Web Frameworks: A Comprehensive Guide

Python has become one of the most popular programming languages, with a market share of 28%. Large corporations like Google and Netflix rely on Python’s reliability and efficiency for web development. However, Python does not include built-in options for generating complex web applications on the fly. To overcome this, developers use elaborate frameworks that manage the specifics of execution and intuitively ease the process of development.

In this guide, we will explore the top Python web frameworks to use for web development in 2024.

What are Python Web Frameworks?

A Python web framework is a set of packages or modules designed to allow a programmer to design web applications or services with as much abstraction as possible from low-level details like protocols, sockets, or process/thread creation. These frameworks help with request filtering, generating responses, and storing data persistently.

Top Python Web Frameworks

1. Django

Django is a high-level Python web framework that enables fast creation of complex codes and applications. It is primarily used to build APIs and web apps, comprising approximately 12000 projects. Django is popular due to its great libraries, less code to be written, and reusability of components.

Advantages: specifies URLs that applications should use, integrated authentication system, effective URL scheme, and supports multiple cache mechanisms. Limitations: slightly less suitable for small-scale projects and undergraduate levels, can cause a slow website depending on the number of requests, and does not have coding conventions like that of Rails.

The Django framework is widely used for building complex web applications.

2. CherryPy

CherryPy is a lightweight, fast, and very stable web application framework. It is open-source and can be used while developing any frame of a Python-supported project.

Advantages: reliable, HTTP/1.1 fully threaded, 1-compliant WSGI web server and thread-pooling, can fire up several HTTP servers at the same instance, and supports Python 2.7+, Python 3.5+, PyPy, Jython, and for Android. Limitations: lack of documentation creates a problem for beginners.

3. Pyramid

Pyramid is another Python web framework that is employed today by Context, Mozilla, Yelp, Dropbox, and SurveyMonkey. It is extendable as well as easy to use, enabling the development of applications of small size as well as of greater size.

Advantages: works well with applications regardless of the size of the application, URL mapping or URL dispatch, clear client brief and template design and asset specification, and vast data documentation, testing, and support. Limitations: requires advanced tool preparation, ideally recommended for dealing with developers with a lot of experience, and is not always beneficial when working on small projects because SQLAlchemy creates an extra layer between the application and the databases that often complicates things.

Pyramid is a flexible and easy-to-use web framework.

4. Grok

Grok, which is built on top of the Zope toolkit, champions “Conventions over Configuration” as well as the “Do not Repeat Yourself (DRY)” paradigms. It boosts the speed of developing applications and development teams by providing with an opportunity to select among different network and standalone libraries.

Advantages: starting up a business for complex web applications, utilizes Zope 3’s capabilities, strong object storage database, integrated data security, and simplifies the development by reducing the uncertainty of Grok component architecture. Limitations: inlining code in parent classes can be a downside because the code becomes less visible, and is pretty much overkill for most view specializations.

5. TurboGears

TurboGears is another Python web framework that is built in Python and can be defined as a data-centric full-stack web framework that resolves major issues of existing web and mobile applications.

Advantages: the features that have been embodied here are known as function decorators, supports multiple databases, command-line utilities available, incorporates the usage of the MochiKit library into JavaScript, and PasteScript templates apply in the MVC architecture. Limitations: may not be easy to grow if there is a need.

TurboGears is a data-centric full-stack web framework.

6. Web2Py

Web2Py has a debugger, a code editor, and a development tool for application testing and administration. It runs on Windows, Unix/Linux, Mac, and on Google App Engine.

Advantages: facilitates rapid web development, MVC Architecture support, connects with Relational and No-SQL DBMS, web-based IDE expedites tasks, and plays a role in security as it resolves issues that threaten the stability of the facility. Limitations: inflexible plug-in system, loading of data models challenges in system management, and no Python 3 support.

7. Flask

Flask, while borrowing the Sinatra Ruby framework, is BSD licensed. It employs the Werkzeug WSGI toolkit and Jinja2 template and has scalability as some of its features.

Advantages: integrated development environment with the debugger server, RESTful request dispatching, integrated unit testing support, uses Jinja2 templating, 100% WSGI 1.0 compatible, and community-developed extensions. Limitations: a complex system which is why it needs developers of high quality.

Flask is a micro web framework that provides the basics needed for web development.

8. Bottle

Bottle is one of the small-scale frameworks which is specifically developed for building Web API’s. It compiles and runs all in a source page and does not call for anything outside the Python Standard Library.

Advantages: API Styled Item/Resource Naming and Basic URL Structures, the fast web application supporting wiki with template engine to product new page, working with CGI and other HTTP servers, and allows to interact with data, cookies, file upload, and other HTTP-related information. Limitations: they are suitable only for small applications, and little information is available about such a community and few successful cases.

9. Tornado

Tornado is a non-created I/O that solves the C10K issue; it is perfect for large numbers of users concurrently.

Advantages: in addition to the user-authentication module, it intends to incorporate third-party authentication and authorization functionalities, provides high-quality, real-time services, provides HTTP clients that do not require locking, facilities translation and localization, and it is used to support user authentication and web templates. Limitations: an overkill for the unique view functionalities.

10. BlueBream

BlueBream is an open-source framework that was earlier called Zope 3, it fits medium to large-scale operations arranged in reusable parts. It depends on the Zope Toolkit (ZTK).

Advantages: WSGI compatibility with Python, approaches to unit and functional testing, security-focused approach, XHTML-compliant language for templates, form generation tool, and you’ll find here that ZCA is great for building really solid components that are easy to reuse. Limitations: high learning curve, not suitable for common tasks, it is less popular and also shows few resources are available, and as for the benefits, performance can be slower for large projects.

Conclusion

Thus, the decision on which Python web framework to use should be based on the requirements of the project. of them, Django and Flask are used frequently for the extent of functionalities the two offer and the flexibility they provide. For smaller projects, the best solutions in terms of simplicity and speed are Bottle and CherryPy. There are far more sophisticated approaches available for more complicated uses; the Pyramid and Grok frameworks are examples of these. Both frameworks have their advantages and disadvantages, and hence they need to be assessed before using them for an organization’s development needs and knowledge.

FAQs
