Python is a popular programming language that is loved by developers all over the world for its speed, reliability and functionality. It is widely used by big companies to build websites. Python helps developers save time by providing ready-made components that they can use in their projects.

Although Python doesn’t have built-in tools specifically for quickly building custom web apps, it has a large collection of libraries that fill this gap. Python is also good for building mobile apps. In this blog, we’ll look at the top 10 Python frameworks that are important to anyone looking to develop web applications, providing useful tips for businesses to consider.

What Is Python?

Python is a flexible programming language that is easy to use because of its simple way of writing code and helpful tools, making it a favorite for creating websites, computer programs, mobile applications and games. Python is also popular for new technologies like machine learning, AI, data analysis and automating tasks.

What Is a Framework?

A framework is a set of tools that help developers build applications quickly by providing ready-to-use code. This saves developers from manually writing a lot of basic code, speeding up the application creation process.

Frameworks and libraries are similar in that they both offer pre-written code that developers can use. However, they differ in how much control the developer has over how the application works. With libraries, developers can decide how to put the application together. A framework, on the other hand, has a set way of building apps, which developers follow to make their apps work properly.
