Action attribute

As explained in A Pythonic Adventure: From Python basics to a working web app

An action attribute is an HTML form attribute specifying the address to which submitted form data is sent.

An action attribute tells the browser where to send form data after submission. In a coffee-order form, action="/order" sends the selected drink to the /order address for processing. section 10.0

Sending a drink order

A form with Coffee and Decaf options uses action="/order" and method="post". Flask receives the submission at /order, reads the drink value, and can print or display the order.
