Flask
Flask is a lightweight, micro web framework for Python that provides essential tools and libraries for building web applications and APIs. It follows a minimalistic design philosophy, offering core functionality like routing, request handling, and templating, while allowing developers to add extensions for additional features as needed. Flask is known for its simplicity, flexibility, and ease of use, making it popular for small to medium-sized projects and rapid prototyping.
Developers should learn Flask when they need a simple, unopinionated framework for building web applications or RESTful APIs in Python, especially for projects where minimal overhead and quick setup are priorities. It's ideal for prototyping, small-scale applications, and microservices, as it allows fine-grained control over components and integrates well with other Python libraries. Flask is also a great choice for beginners in web development due to its straightforward documentation and gentle learning curve.
