Ansible - multiple if else statement or case alternative

Ansible prefer to use when: statement and not have classic implementation of if else or case statement

To use many if statement you can use simple trick.
Example check many variables and depend of this value (if variable is different than empty string '') counting latest occurrence of "not null" value


- name: count number of nic
  vars:
    count_nic: "{{ 5 if NETWORK_5 != '' else '4' if NETWORK_4 != '' else '3' if NETWORK_3 != '' else '2' if NETWORK_2 != '' else '1'}}"
#import playbook based on variable
  include: tasks/nic_{{ count_nic }}.yml
  register: count_nic
