Top Python Frameworks for Web Development for Building a Successful Web App

Python is steadily increasing in popularity and remains the second most common language in the world, with 11.3 million software developers using it around the globe.

Aside from computer science, Python language has proven to be effective for plenty of other areas, such as statistics, data analysis, physics, economics, electronics, and even the sociology department offers an introductory programming course for the students.

Python is one of the fastest-growing and most powerful languages with easy-to-use syntax, dynamic semantics, and hundreds of robust libraries and frameworks, which is extensively used for web development as well as for big data, machine learning, and artificial intelligence.

The world's largest companies such as Amazon, Spotify, Quora, and Google are employing the Python web development framework because they always search for innovative technologies and solutions and want to develop advanced applications suiting many requirements.

According to the latest reports, about 42% of developers claimed that they are using Python as their primary language. Apparently, there are plenty of Python frameworks and features that make it stand out among other web development languages. Let’s check out the key Python frameworks for web development every software engineer should consider before developing websites.

What are Python Frameworks for Web Development?

Python is an excellent language to learn to create programs for both newcomers and experienced developers as it emphasizes code readability and features numerous frameworks that aim to cushion the whole software development project.

Python frameworks automate common application building processes and implementation with the help of the programming language.

To be more specific, Python frameworks provide the foundation to build the program on top of, which significantly contributes to the time-efficiency as engineers don't have to start developing from scratch and can focus on the application logic without handling low-level details and dealing with repetitive functions.

By the way, the difference between frameworks and libraries isn't always clear. Although both libraries and frameworks are reusable pieces of code, they are not interchangeable: while frameworks offer the architecture of the application, libraries provide the collection of packages that performs a specific set of tasks and operations.

Why are Python Frameworks Significant for Web Development?

Advantages of Python Frameworks

Even though Python frameworks are not an integral part of building applications, they play a significant role as these frameworks facilitate the development by providing particular functionality and allow software engineers to re-use generic modules, and instead of executing routine processes, developers can concentrate on more specific components.

So when software engineers start building a Python-based app, they usually consider an array of Python frameworks for their project and choose the most appropriate one.

The core advantages of the Python web frameworks that demonstrate their importance for web development are:

  • Top-notch protection

Built by experienced software engineers, frameworks take care of safety and, therefore, boast effective protection against a number of attacks and threats and give developers tools to avoid mistakes causing security problems.

  • A strong community of developers and users

An ever-growing community of professionals, who improve the platform on an ongoing basis, can provide an immediate response to any problem that may arise. In addition, communities of users offer detailed documentation and articles to give answers to all questions.

  • Reducing time and money spent on development

With frameworks, you receive the fundamental structure, which allows you to avoid reinventing the wheel, and thus you save both time and costs in creating an application and deployment, and therefore improve the overall efficiency.

  • Flexibility

Due to the high flexibility, frameworks are used to develop micro functions as well as to support the front-end and back-end development for larger projects.

Types of Python Frameworks for Web Development

Typically, Python frameworks are divided into three categories, which are full-stack frameworks, micro-frameworks, and asynchronous frameworks.

Let's find out the meaning of each type:

  • Full-stack framework

As the name implies, the full-stack type is a framework that provides the tech solutions for two basic parts of development: front-end (also known as the client-side) and back-end (the server-side). This category of frameworks is used for any type of application.

  • Micro-framework

Unlike a full-stack framework, a micro-framework is a lightweight type that refers to a minimalistic web application, which lacks most of the functionality you might meet in a full-fledged web application framework, like authentication, authorization, and data abstraction layer.

  • Asynchronous framework

The foundation for Python asynchronous frameworks is the asyncio library that is applied to create concurrent code using the async syntax.
