How to get the dead letter queue for a given SQS queue using boto3?

Question

Using boto3 resource, how can I get the DLQ for a particular SQS queue?

I thought it was dead_letter_source_queues, but the use case is reversed.

You would call get_queue_attributes and check the RedrivePolicy.deadLetterTargetArn value in the response.
