When you render your template, you may pass range

render_to_response('template_x.html', {'range5': range(5)})

And in html template, probably like this

{% for i in range5 %}
    <div class="tab-content">
    <h1 class="tab" title="title for page {{i}}">Page {{i}}</h1>
    <p>This is the content of tab {{i}} on container {{i}}</p>
    </div>  
{% endfor %}

I guess you are not good at searching, right (:

A good documentation for a good framework... On the other hand, why you ask for a c-like loop structure in a framework written for python is another question

EDIT: For loop in django templates iterates through an array (or list in python terms). So you have to have a list to iterate.. In your related view, lets say yopu have a number list

number_list = [1,2,3,4,5]

if you pass this list to the template with the same name, then you can iterate through it with

{%for num in nuber_list%}
    Number is : {{num}}
{%endfor%}

But as i said, you have to pass that list to template in the return statement line that returns an httpresponse or render your contect to your template as it described in here

I was curious and found a way to do this. Disclaimer: I consider the following code to be WRONG:

{% for i in "abcde" %} do something {% endfor %}

Replace "abcde" with a string of the range you want.
