Hello world!

Im trieng to build my own template tags Im have no idea why I get the errors I get, im following the django doc's.

this is my file structure of my app:

pollquiz/
    __init__.py
    show_pollquiz.html
    showpollquiz.py

This is showpollquiz.py:

from django import template
from pollquiz.models import PollQuiz, Choice
register = template.Library()

@register.inclusion_tag('show_pollquiz.html')
def show_poll():
    poll = Choice.objects.all()
    return { 'poll' : poll }

html file:

<ul>
{% for poll in poll 
    <li>{{ poll.pollquiz }}</li>
{% endfor 
</ul>

in my base.html file im am including like this

{% load showpollquiz %}
and
{% poll_quiz %}

Bu then I get the the error:

Exception Value: Caught an exception while rendering: show_pollquiz.html

I have no idea why this happens. Any ideas? Please keep in mind Im still new to Django
