How to use flask.redirect method

Flask is a micro web framework. It is lightweight, simple, and easy to use. It helps in building web applications and web services in Python.

Flask is described as a "micro" framework. It provides the web development components without imposing a much-predefined structure.  

Key aspects of Flask:   

1. Lightweight: The Flask is minimalistic. It only comes bundled with a few built-in features. Instead, it provides the basic routing, request handling, and response generation tools. It allows developers to add features as needed.  
2. Extensible: Flask is easily extended with third-party extensions and libraries. This modular approach means you can add features by including the relevant extensions. It can include authentication, database integration, or session management. 
3. WSGI Compliant: Flask is WSGI (Web Server Gateway Interface) compliant. It can run on web servers supporting WSGI, such as Guni corn, uWSGI, or Apache with mod_wsgi.  
4. URL Routing: Flask provides a way to define and associate URL routes. It makes it easy to create a RESTful API or build web pages with different routes.  
5. Template Support: Flask includes a templating engine called Jinja2. It helps separate the presentation layer from the application logic. This allows you to create dynamic HTML pages with placeholders. We can fill it with data from your Python code.  
6. Request Handling: Flask makes handling HTTP requests easy and helps access client data. 
7. Response Generation: You can generate HTTP responses using Flask'sFlask's built-in functions.  
8. Development Server: It comes with a built-in development server. It helps in testing your applications during development.  

In summary, the redirect method in Flask is a valuable tool. It helps manage user navigation and send them to different parts of your web application. It simplifies the process of handling HTTP redirects. It makes creating an interactive user experience in your web application easier.
