It works for me. Running in the shell

$ python app.py 
 * Running on (Press CTRL+C to quit)
 * Restarting with stat - - [17/Feb/2016 18:12:58] "GET / HTTP/1.1" 200 - - - [17/Feb/2016 18:12:58] "GET /favicon.ico HTTP/1.1" 200 - - - [17/Feb/2016 18:12:59] "GET /favicon.ico HTTP/1.1" 200 -

At url I see:

hello from rodney
