No se pudo analizar el resto de Django.

He estado intentando escribir una etiqueta de plantilla personalizada para acortar enlaces con bitly, he adjuntado el código y el error que he estado recibiendo a continuación. He intentado buscar en la documentación proporcionada por Django pero no puedo ver qué es lo que estoy haciendo mal.

He puesto mi templatetag en el siguiente diseño:

scribbler/
    models.py
    templatetags/
        __init__.py
        shortenlink.py
    views.py

el archivo de etiqueta personalizada que he escrito:

shortenlink.py

from django import template
from django.conf import settings
from urllib import urlencode
from urllib2 import urlopen

register = template.Library()

@register.simple_tag
def bitlyshort(the_url):
    endpoint = 'https://api-ssl.bitly.com/v3/shorten?access_token={0}&longUrl={1}&format=txt'
    req = urlencode(endpoint.format(settings.ACCESS_KEY, the_url))
    return urlopen(req).read()

parte de la plantilla que usa la etiqueta de plantilla:

modelo

{% load shortenlink %}
<p>{{ bitlyshort "http://www.google.com" }}</p>

error
