title: Key with multiple values - check if value is in dictionary python
body: <p>I have a dictionary that has a list of multiple values stored for each key. I want to check if a given value is in the dictionary, but this doesn't work:</p>
  
  <pre><code>if 'the' in d.values():
      print "value in dictionary"
  </code></pre>
  
  <p>Why doesn't it work with multiple values stored as a list? Is there any other way to test if the value is in the dictionary? </p>
