I would like to save data returned from action "hostnametoip" in the service yang model acl_rule_ip. But I am not able to figure out Python code which would be able to call the Service from Action class.
It will be great if someone could help me figure out this 
Thanks
Thanks , it did help
I was trying to create an action for converting hostname to ip in ACL since a user may want to add/delete a hostname before pushing.
with ncs.maapi.single_write_trans('admin', 'python') as th:
root = maagic.get_root(th)
svc = root.services.nso_acl_python[kp[2][0]].CR_ID_QUEUE[kp[0][0]]
self.log.info("svc",svc)
svc.acl_rule_ip = output.acl_rule_ip
th.apply()
it worked for me
