Flask

Flask is a lightweight Python web framework that provides the essential tools for building web applications without enforcing a specific project structure. It follows a micro-framework philosophy, offering minimal built-in functionality while allowing developers to add extensions as needed. Flask is widely used for building APIs, web applications, microservices, and prototypes in the Python ecosystem. It includes a development server, integrated debugger, built-in support for unit testing, and Jinja2 templating engine. Flask is particularly popular in the data science and machine learning communities for creating web interfaces to models and services. The framework emphasizes simplicity, flexibility, and fine-grained control over application components. Flask has a large ecosystem of extensions for database integration, authentication, form validation, and other common web development tasks.
