title: How to get the difference between two dictionaries in Python?
body: <p>I have two dictionaries, and I need to find the difference between the two, which should give me both a key and a value.</p>
  <p>I have searched and found some addons/packages like datadiff and dictdiff-master, but when I try to import them in Python 2.7, it says that no such modules are defined.</p>
  <p>I used a set here:</p>
  <pre class="lang-py prettyprint-override"><code>first_dict = {}
  second_dict = {}
   
  value = set(second_dict) - set(first_dict)
  print value
  </code></pre>
  <p>My output is:</p>
  <pre class="lang-py prettyprint-override"><code>&gt;&gt;&gt; set(['SCD-3547', 'SCD-3456'])
  </code></pre>
  <p>I am getting only keys, and I need to also get the values.</p>
