When you look at the exported symbols, there is no route, so if you 
expected flask to export route it is not there either.

There is 2 possibilities here. One is you have a module named route. 
Than you do not import it as a name from flask, but as a module.

The other is you are looking for the attribute route from the Flask class.

@app.route("/item/<item_no>", methods=["GET", "POST"])

This creates a route. The route method is a method of an instance of 
Flask (i.e. app), so importing Flask is enough.

Yes, that is OK, if DNS contains a host superhost.gr.
