How to control looping with Django

I am trying to use the Django template to loop over a set of records, but stop one short, and then process the last one differently. So lets say I have 50 records - I would want to loop over 1 to 49 and then stop, and then process the 50th outside the loop. I am trying to create

    [[date, var2],[date, var2],..[date, var2]*];

I am using:

    data.addRows([
      {% for data in mydata %}
         [{{data.date}},{{data.var2}}],
      {% endfor %}
    ]);

My aim is to NOT include the comma (indicated by the *) but to keep the required form. Any help would be appreciated. Thanks.

What you are looking for is forloop.last that makes it possible to do this task entirely within the loop.

data.addRows([
      {% for data in mydata %}
         {% if forloop.last %}
             [{{data.date}},{{data.var2}}]
         {% else %}
             [{{data.date}},{{data.var2}}],
         {% endif %}
      {% endfor %}
    ]);

There is an alternative, the last filter which returns the last item on a list, but the above method is the more conventional way of doing this.
