Of course, with variables you can do almost everyting.

&nbsp;&nbsp;- debug: var=item  
&nbsp;&nbsp;&nbsp;&nbsp;with\_sequence: end={{ number }}

ansible-playbook -e number=3

```auto
- gather_facts: false
  hosts: localhost
  tasks:
    - set_fact:
        db: "{{ lookup('password', '/dev/null chars=ascii_letters,digits length=32') }}"
        usr: "{{ lookup('password', '/dev/null chars=ascii_letters,digits length=39') }}"
        password: "{{ lookup('password', '/dev/null chars=ascii_letters,digits length=21') + '' }}"
      with_sequence: end={{ number }}
    - local_action: shell echo "{{ db }}__{{ usr }} {{ db }} {{ password }}" >> /tmp/pass_pokus3

```

you are overwriting the variables on each loop, and then you are NOT  
looping the shell action. Remove the set fact and use the lookups and  
loop directly on the shell action.
