Read the documentation for the {% for %} template tag - it sets a
{{ forloop.counter }} variable.
http://docs.djangoproject.com/en/dev/ref/templates/builtins/#for
You may also want to have a look at the {% cycle %} tag (same page as
above), and / or be interested in the "partition" filters on
djangosnippets:
