Flask

Flask is a lightweight framework for building web applications using Python. It provides the tools to create websites, APIs, and services by handling requests from users, processing data, and delivering responses such as web pages or data. Flask offers flexibility, allowing developers to build simple to complex applications with minimal setup, by providing essential components like routing (to define URL behaviors) and templates (to generate HTML content). It's popular for its simplicity and extensibility, making it a preferred choice for developers who want to quickly develop web functionality in Python.
