Reference variables in expressions in Ansible/Jinja

I'm trying to figure out how I can reference a dictionary item in a variable based on another variable. For example:

{{ myVariable.someItem.someVariableItem.someOtherItem }}

Essentially, myVariable is (obviously) a variable, but I want the item someVariableItem to be set elsewhere. Is this possible?

Yes. It's possible.

"{{ myVariable.someItem[someVariableItem].someOtherItem }}"

For example the play below

- hosts: localhost
  vars:
    my_variable_item: item_z
    my_dict:
      item_x:
        other_item_a: 1
      item_y:
        other_item_b: 2
      item_z:
        other_item_c: 3
  tasks:
    - debug:
        msg: '{{ my_dict[my_variable_item].other_item_c }}'

gives

"msg": "3"
