How to find AWS Load Balancer ARN from its name with python api?

Question

Given a load balancer name, is it possible to find its ARN with AWS API? The closest I see is the describe_load_balancers function, but its output doesn't include ARN. Am I missing something simple?

Full context: The script adds "DDoSAttackBitsPerSecond" metrics to a AWS Dashboard, and metric description includes the ARN of the load balancer as one of its dimensions.

Any suggestions appreciated,

Mike

Doh, I was using boto3.client('elb'), which doesn't return ARN, instead of boto3.client('elbv2'), which does. I hope someone will find this useful...
