I'm trying to concatenate registered variable from a previous task , external variable with a string ( ex: -stringhere) in a task.

I'm not getting the syntax to do it.

I tried below and it didn't work.

Command : echo {{ item.0 + "-" item.1 +"-stringhere"  
With\_items:  
&nbsp;&nbsp;&nbsp;- "{{ thevar.stdout }}  
&nbsp;&nbsp;&nbsp;&nbsp;- "{{ external var }}"

Please help with the syntax to do this.
