Play book to install multiple packages then restart services using with_items:

Writing a play book to install multiple packages using vars and then restart  services using  with_items:
Starting multiple services using with_items:
You can use the with_items parameter to control multiple services in a single task.
Note: Make sure the {{ item }} is within quotes, and the with_items block need to be intended at the level of module name in our case its -here systemd. The following example will restart nfs-utils and httpd, a daemon reload before it restarts the service.
