Answer 1

The line `@app.route('/')` is a decorator in Flask, a web framework for Python, that tells the application which function to execute when a user accesses the root URL (i.e., the homepage) of the web application. It essentially maps the URL path `'/'` to a specific function that will handle the request made to that URL, allowing you to define what content to display when a user visits that page.
