As the output of some shell-command is not per se delimited to one single value, registering it creates a list.

Thus, using “{{ some\_list }}” get’s you square-brackets around the list of values - although in your case, it’s a list with just one single value.

Besides omitting the parameter, you could for instance join the list to a string: “{{ drive\_for\_lvm | join ‘’ }}”, see [https://docs.ansible.com/ansible/playbooks\_filters.html#id7](https://docs.ansible.com/ansible/playbooks_filters.html#id7)  
… or you could limit the list to its first element, either with “{{ drive\_for\_lvm[0] }}” or “{{ drive\_for\_lvm | first }}”, see again the filters or [https://docs.ansible.com/ansible/playbooks\_variables.html#accessing-complex-variable-data](https://docs.ansible.com/ansible/playbooks_variables.html#accessing-complex-variable-data)
