The 8 Best Python Frameworks for Web Applications and Services

Python was ranked as one of the most popular programming languages in 2021, with over 48% of developers trusting it for various projects. But what is a Python framework? Is it the same as the Python coding language? First of all, Python is treated more like a language for machine learning (ML), data science, and IoT (internet of things).

Now to put it simply, Python frameworks are a collection of modules and packages that let developers write web applications and services fast and efficiently. This article will teach you about the most popular Python frameworks in high demand. So, let’s dive in!

The easy learning curve of the coding syntax and standard collection of libraries make Python a go-to choice for web technologies. This is why top brands like Google, Spotify, and Pinterest use it as their core programming language.

Categories of Python Web Development Frameworks

Essentially, you can categorize the Python web development frameworks into three types. But what makes each class unique? Let’s walk you through it:

  • Full-stack frameworks. Also known as an enterprise framework, a full-stack framework is a one-stop solution for all your development needs. These have built-in libraries that are configured to work seamlessly with each other. They also support frontend interfaces, backend services, and the integration of databases.
  • Microframeworks. Microframeworks are minimalistic frameworks with limited features and functionalities. Compared to full-stack frameworks, microframeworks are lightweight. A lightweight and minimalistic web app framework might be enough if you were to build an application with only the essentials. They lack additional features and functionalities, such as a database abstraction layer, web template engine, form validation, and input validation. But the components they offer are enough for building an application.
  • Asynchronous framework. An asynchronous framework is a unique type of microframework that can let the developers manage and handle a large set of concurrent connections. The latest addition to the Python framework, Bandwagon, is an asynchronous framework. These frameworks feed on the Asyncio library of Python.

Types of python frameworks

Keep in mind the various categories of Python frameworks because next, we will discuss the necessity of using frameworks. 

What Are the Advantages of Using a Framework?

In essence, frameworks provide the packages and tools that help make the development process much easier. Developers widely use them to reuse the code of similar types of HTTP operations. Frameworks are also a go-to option for developers who want to define an application structure with predefined functionalities.

Frameworks also ease the process of debugging and application maintenance. Loads of programming languages do not emphasize the robustness and readability of the code. Frameworks are not one of them. Although a framework-adapted programming language is highly suggested for reliability and extending functionalities, what counts for most developers is how it makes maintenance and debugging easy.

Furthermore, frameworks do not need to write long lines of code. Instead, developers add common patterns to their website applications. In short, frameworks introduce quickness and higher clarity in the code section. By doing so, frameworks reduce the additional time and effort developers have to put into a project without them.

But before you choose a random framework, you should consider some essential factors.

Things to Consider Before Choosing the Best Python Framework

Before diving into the best Python frameworks list, you need to know what to factor in before choosing a framework for Python.

How to choose the best python frameworks
  • Size of the project. Full-stack frameworks will be the best fit if you aim to develop a large-packed system with advanced modules and features. On the contrary, microframeworks would be best if the project has low requirements.
  • Scalability of the framework. Check whether the framework can scale horizontally or vertically. This consideration will be highly relevant if your websites will run on numerous servers and will continuously handle heavy traffic.
  • MVC (multi-view controller). It is common in all Python frameworks, and its main task is to maintain the logic (controller), data (model), and UI (view). Eventually, MVC allows developers to write codes in a better format, which will ultimately convert to qualitative projects.
  • Budget and hosting. It is normal to aim to develop a cutting-edge platform. Likewise, it is natural to worry about the budget. Dedicated hosting is superior, but the cost is higher than shared hosting. On the other hand, shared hosting is comparatively cheaper but offers mediocre plugins and modules.
  • Installation. One of the crucial factors in terms of adopting a Python framework is the installation steps. Some fast and highly efficient frameworks require developers to complete a complicated installation process. These demanding installation steps can indeed impact the application itself because you might not be able to deploy it to the production server.
  • Learning resources. You should put learning resources on your consideration list. Developers benefit the most when they select the one with the least learning curve. Remember that each Python framework has its dictionary and terms. Consider them before choosing one.
  • Core library. The core library is another factor you should emphasize while choosing a Python framework. And when it comes to the evaluation core library, consider whether it provides the flexibility of writing a piece of code while offering the ability to tinker with it if you want more options or control over your program.
  • Documentation and requirements. It would be best if you focus more on frameworks with extensive documentation. Look for examples, sample codes, tutorials, snippets, and blogs. On the other hand, in terms of requirements, it will depend on the project. Check what the project demands and choose the one that is best suited for it.

After covering the most important factors, it’s time to check some examples of Python frameworks.

We have selected the eight most popular Python frameworks for web and app development. Each of them has its unique features and caters to different needs. The following is a list of some of the best Python frameworks, based on popularity and ability to provide rapid web and app development:

Best Python frameworks

Flask

Flask is classified as a microframework. Why? It does not need libraries or tools. It does not have advanced features, such as form validation and database abstraction layer, but it contains many extensions. When experienced developers need a simple web server that is fast enough to serve a simple website, they would most likely resort to Flask.
