flask is a popular micro - web framework for python. it offers simplicity and flexibility, making it ideal for web development, especially for beginners and small - to - medium - sized projects.
one of the key advantages of flask is its lightweight nature. it doesn't impose a lot of pre - defined structures, allowing developers to choose the components they need, such as databases and authentication methods. for example, integrating a sqlite database is straightforward.
routing in flask is intuitive. by using the `@app.route` decorator, developers can easily define url endpoints and the corresponding functions to handle requests. flask also supports templating engines like jinja2, enabling the creation of dynamic web pages. overall, flask provides a great foundation for building web applications efficiently with python.
