Creating web applications with Flask
Flask is a lightweight WSGI web application framework. It's designed to make getting started quick and easy, with the ability to scale up to complex applications. Flask provides routing, request handling, template rendering, and session management out of the box. It follows a micro-framework approach, meaning it keeps the core simple but extensible. Extensions provide additional functionality like database integration, form validation, authentication, etc. A basic Flask application involves creating an instance of the Flask class, defining routes with decorators, and running the application. Flask uses Jinja2 for templating, which allows embedding Python-like expressions in HTML. Understanding Flask basics provides a foundation for web development in Python and makes it easier to learn other frameworks. Flask's simplicity and flexibility make it popular for prototypes, small applications, and learning web development concepts.
