Relating to gameweld's answer, since Ansible 2.5 there's another way to accessing the iteration index.

From the docs:

Tracking progress through a loop with index_var

New in version 2.5.

To keep track of where you are in a loop, use the index_var directive with loop_control. This directive specifies a variable name to contain the current loop index:

- name: count our fruit
  debug:
    msg: "{{ item }} with index {{ my_idx }}"
  loop:
    - apple
    - banana
    - pear
  loop_control:
    index_var: my_idx

This also allows you to gather results from an array and act later to the same array, taking into account the previous results

- name: Ensure directories exist
  file:
    path: "{{ item }}"
    state: directory
  loop:
    - "mouse"
    - "lizard"
  register: reg

- name: Do something only if directory is new
  debug:
    msg: "New dir created with name '{{ item }}'"
  loop:
   - "mouse"
   - "lizard"
  loop_control:
    index_var: index
  when: reg.results[index].changed

Please note that the "mouse lizard" array should be exactly the same
