# Jinja loop example:
{% set l = [1,2,3,4,5,6,7] %}
{% set count = [1] %}
{% for i in l %}
{% if count.append(count.pop() + 1) %}{% endif %} {# increment count by 1 #}
{% endfor %}

test:
  test.nop:
    - bla: |
        {{ count }}


# Example how POP working:
root@scm-master:/srv/salt# cat test.sls
{% set l = [7,6,5,4,3,2,1] %}
Example with list:
  test.nop:
    - bla: |
        {{ l }}
        {{ l.pop() }}
        {{ l }}
        {{ l.pop(4) }}

{% set d = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5, 'i': 6, 'f': 7, 'j': 8} %}
Example with dict:
  test.nop:
    - bla: |
        {{ d }}
        {{ d.pop('i') }}
        {{ d }}
