title: Boto: Find if bucket is public or private
body: <p>I don't find a way to easily know if my AWS S3 buckets are public or private. </p>
  
  <p>I was expecting to do <code>list_bucket_response = s3client.list_buckets()</code> and directly know if the bucket is publicly accessible or not.
  I've came across <a href="https://jgreenemi.com/how-to-check-if-your-s3-buckets-allow-public-read-acls/" rel="nofollow noreferrer">https://jgreenemi.com/how-to-check-if-your-s3-buckets-allow-public-read-acls/</a> but in my case when I list buckets I don't get an URI.</p>
  
  <p>I also tried <code>s3client.get_bucket_acl(Bucket=bucket_name)</code> without success.</p>
