title: Get elasticloadbalancers names with boto3
body: <p>When I try to print the load balancers from aws I get a huge dictionary with a lot of keys, but when I'm trying to print only the 'LoadBalancerName' value I get: None, I want to print all the load balancers names in our environment how I can do it? thanks!
  What I tried: </p>
  
  <pre class="lang-py prettyprint-override"><code>import boto3
  client = boto3.client('elbv2')
  elb = client.describe_load_balancers()
  Name = elb.get('LoadBalancerName')
  print(Name)
  </code></pre>
