... there is no "run" there. What were you trying to achieve?
When you look at the exported symbols, there is no route, so if you 
expected flask to export route it is not there either.
How is that even possible?

Do i have  something wrong in the www.py?

from flask import Flask, route, request, redirect, render_template, url_for, 
send_from_directory, debug

app = Flask(__name__)
app.run(debug=True)

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.

Also i use run for this

app.run( host='superhost.gr', port=5000, debug=True )

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