Como excluir uma política

O exemplo a seguir mostra como excluir uma política de uma organização. O exemplo pressupõe que você já separou a política de todas as entidades:

aws organizations delete-policy --policy-id p-examplepolicyid111

def delete_policy(policy_id, orgs_client):
    """
    Deletes a policy.

    :param policy_id: The ID of the policy to delete.
    :param orgs_client: The Boto3 Organizations client.
    """
    try:
        orgs_client.delete_policy(PolicyId=policy_id)
        logger.info("Deleted policy %s.", policy_id)
    except ClientError:
        logger.exception("Couldn't delete policy %s.", policy_id)
        raise
