How to loop ansible variables

i have the below yml file which is working as expected

---
- hosts: local
- name: Example of provisioning servers
hosts: 127.0.0.1
connection: local
tasks:
- name: Modify security group
  local_action:
    module: ec2_group
    name: ansible_trail
    description: Modify SG Rules
    region: us-east-1
    rules:
      - proto: tcp
        from_port: 22
        to_port: 22
        cidr_ip: 198.168.45.23
    purge_rules: true*

i want to repeat the same action for all of my security groups how to do that in ansible .

instead of assigning the name: optv5_ansible_trail i want to get the value from list or file.
