Python web frameworks: HTML server-side templates and duplication of code

I'm experimenting Python web frameworks and HTML templates. The concept seems restricted, compared to generating entire HTML code on the fly. For instance, to generate a combo box, I found the following Django templating example:

<select id="{{ item.name }}" name="{{ item.name }}">
{% for choice in item.choices %}
  {% ifequal item.value choice %}
  <option value="{{ choice }}" selected>{{ choice }}</A>
  {% else %}
  <option value="{{ choice }}">{{ choice }}</A>
  {% endifequal %}
{% endfor %}
</select>

The ifequal statement duplicates entire code just to add a "selected" attribute to the selected option. It seems to me this becomes a burden in HTML tags with several attributes and which some few attributes exist or not depending on a condition. Is the above snippet a bad usage of templating? Is there a better way to implement the combo box using it?

It can be written in a single line in this way. 

<option value="{{ choice }}" {% ifequal item.value choice %}selected="selected"{% endifequal %}>{{ choice }}</option>
