It was just a guess, but as the OP uses bottle, here's a modified 
"hello world" from the bottle site 
<http://bottlepy.org/docs/dev/tutorial.html#quickstart-hello-world>:

$ cat app.py 
from bottle import route, run

@route('/hello')
def hello():
    yield "Hello "
    yield "World!"

run(host='localhost', port=8080, debug=True)
$ python3 app.py &
[1] 3203
$ Bottle v0.12.7 server starting up (using WSGIRefServer())...
Listening on http://localhost:8080/
Hit Ctrl-C to quit.


$ python3 -c 'from urllib.request import urlopen; print(urlopen("http://localhost:8080/hello").read())'
127.0.0.1 - - [28/Jul/2014 09:07:15] "GET /hello HTTP/1.1" 200 12
b'Hello World!'
