Alternate class in a for loop?

Question

I'm cycling through a list using {% for item in list %} and I want to output something like this:

<li>One</li>
<li class='alternate'>Two</li>
<li>Three</li>
<li class='alternate'>Four</li>
...

with the intention of styling the alternate lines a different colour.

Django (1.3) has no mod or div template tag operators. I know I can add them by manipulating the django source, but I'd rather not do that as I want to be able to package this app up.

How can I achieve this?

@MilkyWayJoe That's awesome, but what's the compatibility like of that syntax? — fredley, Nov 16 '12 at 15:45
IE<=8 don't like this selector. IE>=9 works fine. Other browsers seem to work fine too. — MilkyWayJoe, Nov 16 '12 at 15:55
@MilkyWayJoe Site needs to be compatible back to IE8, so I'll stick with `divisibleby` for now, but thanks for the tip! — fredley, Nov 16 '12 at 15:59

How about django's divisibleby filter...

{% for item in list %}

<li class= "{% if forloop.counter|divisibleby:2 %}alternate{% endif %}"><Your value></li>

{% endfor %}

Alternatively, cycle:

<li {% cycle "class='alternate'" "" %}"
