title: Python Dictionary get value of Key
body: <p>Is there a way to get the <em>value of the key</em>, not the <em>key value</em> in a dictionary? for example:</p>
  
  <pre><code>d = {"testkey": "testvalue"}
  print(d.get("testkey"))
  #OUTPUT: "testvalue"
  </code></pre>
  
  <p>Is there a way to get the String "testkey"? I will have no way of knowing what the String returned will be in the end. Would it be more beneficial to use a list instead of a dictionary?</p>
