Flask

WTForms is a Python library that provides flexible web form rendering. You can use it to render text fields, text areas, password fields, radio buttons, and others. WTForms also uses a CSRF token to provide protection from CSRF attacks. In this tutorial, you’ll build a small web application that demonstrates how to render and validate web forms using Flask-WTF.

Flask is a lightweight Python web framework that provides useful tools and features for creating web applications in the Python Language. In this tutorial, you’ll build a small web application with Flask that demonstrates how to use web forms. The application will have a page for displaying messages that are stored in a Python list, and a page for adding new messages. You’ll also use message flashing to inform users of an error when they submit invalid data.
