what is @app.route('/') doing?

hi, as Ken said, def index(): return 'hello tree house'

is just a function, not a view yet. what makes it a view is a route, and the forward '/' i guess it will give a '/' to the end of web address as shown in video?

so I'm thinking why adding a '/' in the end will make a invalid webpage valid? thx

When a request is submitted to the flask server, the requested URL is compared to the paths registered using the @app.route() decorator.

The forward slash ("/") represents the "web root address". If there is no the content after the domain name and optional port number, for example, a local server URL http://127.0.0.1:8000 would be directed to the above route.
