Why not just add the seperator via CSS? You can use nth-child selector without any extra HTML.

no i just want to be from it any idea?&quest;
how we set

can you please give me soluation how we set

Have a look at the loop variable if you would prefer to add something via Twig/HTML: http://twig.sensiolabs.org/doc/tags/for.html#the-loop-variable

if we want to be write some thing like above any idea how to set it
when we set i++ it giving error

Now i got the solution here we can set

{% set i = 1 %}
{% for ps in taxonomy.findTaxonomy({'Post Type':'blog'})|slice(0, 10) %}
<h2><a href="{{ps.url}}">{{ps.title}}</a></h2>
{% if(i%2==0)%}
<div>for separtor</div>
{% endif%}
{% set i = i + 1 %}
{% endfor %}

we can used something like above

Thanks
