Frameworks

Flask is a microframework for developers, designed to enable them to create and scale web apps quickly and simply.

A micro web framework that has minimal dependencies on external libraries, written in Python, which was formed for a faster and easier use, and also has the ability to scale up to complex applications.

Flask features:

• There are only a handful of parts of flask that cannot be changed or altered because of its simplicity and minimalism. This means that almost all the parts of flask are open to change, unlike some other web frameworks.
• Using Flask for web development allows for unit testing through its integrated support, built-in development server, fast debugger, and restful request dispatching. It is lightweight to enable you to transit into a web framework easily with some extension.
• Size is everything, and Flask's status as a microframework means that you can use it to grow a tech project such as a web app incredibly quickly. If you want to make an app that starts small, but has the potential to grow quickly and in directions you haven't completely worked out yet, then it's an ideal choice. Its simplicity of use and few dependencies enable it to run smoothly even as it scales up and up.
• Flask also supports modular programming, which is where its functionality can be split into several interchangeable modules. Each module acts as an independent building block, which can execute one part of the functionality. Together this means that the whole constituent parts of the structure are flexible, moveable, and testable on their own.

Flask is one of the most popular web frameworks, meaning it's up-to-date and modern. You can easily extend it's functionality. You can scale it up for complex applications.
