Django - Limit the number of objects in Django template

I used to code in C#. I want to use Python to do something like:

int start_index = 4;
List<int> list = { ... }
for(int i = start_index;i < 10;i++){
     list[i].dosomething();
}

This is how I tried in Django 

{% with 0 as starting_index %}
{% for comment in comments %}
<!--set a variable to limit the amount of comment on a page-->
{% with forloop.counter as index %}
{% if index < 3 %}
<div class="comment_body">
    <div class="content_block">
        <p>{{comments[index]}}</p>
    </div>
</div>
{% endif %}
{% endwith %}
{% endfor %}
{% endwith %}

This code is obviously not working. Can anybody help me with this problem? Thanks in advance!

If you want to do this in the template you can use the built in django template tage slice:

{% for new in comments |slice:":3" %}

Slice to the number of objects you want in the template.
