      user:

        shell: /bin/bash

      loop: " {{ users }} "

users:
- uname: linda
  password: password
  department: profs

- uname: lisa
  password: secret
  department: profs

- uname: anna
  password: geheim
  department: students

when running the above mentioned playbook and adding this var file i get the following error:

fatal: [ansible5]: FAILED! => {
    "msg": "Invalid data passed to 'loop', it requires a list, got this instead:  [{'uname': 'linda', 'password': 'password', 'department': 'profs'}, {'uname': 'lisa', 'password': 'secret', 'department': 'profs'}, {'uname': 'anna', 'password': 'geheim', 'department': 'students'}] . Hint: If you passed a list/dict of just one element, try adding wantlist=True to your lookup invocation or use q/query instead of lookup."
}

I really don't understand, I am sure that my declaration of variable is correct. Any help, please?

I think the problem is due to the space within the quotes in variable to loop, i.e. " {{ users }} ". There might be another "hidden" issue in the when condition due to the use of Jinja delimiters {{.

Overall, it should work with changes as below:

    - name: create users who have depart set as profs
      user:
        name: "{{ item.uname }}"
        groups: "{{ item.department }}"
        shell: /bin/bash
        password: "{{ item.password|password_hash('sha256') }}"
      when: item.department == "profs"
      loop: "{{ users }}"
