Variable names can be built by adding strings together. 
For example, if we need to get ipv4 address of an arbitrary interface, 
where the interface to be used may be supplied via a role parameter 
or other input, we can do it in this way.

1{{ hostvars[inventory_hostname]['ansible_' + which_interface]['ipv4']['address'] }}
