title: Difference in boto3 between resource, client, and session?
body: <p>I am using Python 2.7.12 in Ubuntu 16.04 LTS. I'm learning how to use boto3 from the following link: <a href="https://boto3.readthedocs.io/en/latest/guide/quickstart.html#using-boto-3" rel="noreferrer">https://boto3.readthedocs.io/en/latest/guide/quickstart.html#using-boto-3</a>. My doubt is when to use resource, client, or session, and their respective functionality.</p>
