Here is an example of the usage of this function:
Flask is a light web framework written in Python. It’s easy to learn and use and it’s a perfect tool to build website prototypes. For example: in this website
most of the content is static and with the help of Jinja library, it only takes a couple of lines to generate the table. The website does need to store the thumbs-up and thumbs-down data but for a prototype it’s not a big deal and we don’t really need a database.
