title: Counting values in dictionary
body: <p>I have a dictionary as follows.</p>
  
  <pre><code>dictA = { 
      'a' : ('duck','duck','goose'), 
      'b' : ('goose','goose'), 
      'c' : ('duck','duck','duck'), 
      'd' : ('goose'), 
      'e' : ('duck','duck') 
      }
  </code></pre>
  
  <p>I'm hoping to loop through dictA and output a list that will show me the keys in dictA that have more than one "duck" in value.</p>
  
  <p>For example, for dictA this function would output the below list.</p>
  
  <pre><code>list = ['a', 'c', 'e']
  </code></pre>
  
  <p>I'm sure there is an easy way to do this, but I'm new to Python and this has me stumped.</p>
