Flask is a lightweight and flexible Python web framework designed for building web applications quickly and easily. It provides the essentials for routing, request handling, and templating without enforcing a specific project structure, making it highly extensible with third-party libraries. Flask is ideal for both small projects and large applications, providing developers with full control over components such as databases, authentication, and caching, while keeping the core simple and minimal.
