How do I get odd and even values in a Django for loop template?

<div class="row">
{% for post in posts %}
      {% cycle 'odd' 'even' %}
      {% if cycle == 'odd' %}
        <div class="col-md-6">Odd posts</div>
      {% else %}
        <div class="col-md-6">Even posts</div>
      {% endif %}
    {% endfor %}
</div>

OR

<div class="row">
{% for post in posts %}
   {% if forloop.counter|divisibleby:2 %}
        <div class="col-md-6">Even posts</div>
      {% else %}
        <div class="col-md-6">Odd posts</div>
      {% endif %}
    {% endfor %}
</div>

In first level cycle:

{% cycle 'odd' 'even' %}

Reference:

{% if forloop.counter|divisibleby:2 %}even{% else %}odd{% endif %}
