title: How to print multiple items from dictionary
body: <p>I have a VERY basic question here, so please don't laugh. I can't find any specific resolution to this, and the manual I am using does not address this question specifically, probably because it is something really obvious. When using:</p>
  
  <blockquote>
    <p>print residents['tenantA']</p>
  </blockquote>
  
  <p>I get the correct output "<strong>36</strong>" from the dictionary</p>
  
  <blockquote>
    <p>residents = {'tenantA' : 36, 'tenantB' : 37, 'tenantC' : 38}</p>
  </blockquote>
  
  <p>But when I try this with more than one item from the dictionary as follows:</p>
  
  <blockquote>
    <p>print residents['tenantB', 'tenantC']</p>
  </blockquote>
  
  <p>I get the following error:</p>
  
  <blockquote>
    <p>KeyError: ('tenantB', 'tenantC')</p>
  </blockquote>
  
  <p>I have also tried</p>
  
  <blockquote>
    <p>print residents['tenantB' + 'tenantC']</p>
  </blockquote>
  
  <p>but as expected, this just concatenates <strong>tenantB</strong> and <strong>tenantC</strong> to <strong>tenantBtenantC</strong>.</p>
  
  <p>I have also tried:</p>
  
  <blockquote>
    <p>print residents[1:]</p>
  </blockquote>
  
  <p>but then I get the error</p>
  
  <blockquote>
    <p>TypeError: unhashable type</p>
  </blockquote>
  
  <p>The error message does not tell me much. Could anyone let me know what I am missing here?</p>
  
  <p>Thanks.</p>
