title: Difference between dictionary and pandas series in Python
body: <p>I have a requirement to keep data in key value pairs. I search and found 2 ways in python:</p>
  
  <ol>
  <li><p>default data structure dictionary.</p>
  
  <pre><code>x = {'key':value}
  value = x['key']
  </code></pre></li>
  <li><p>series of pandas data structure.</p>
  
  <pre><code>x = pandas.Series({'key':value})
  value = x.key
  </code></pre></li>
  </ol>
  
  <p>I want to know the difference between this two apart from syntax.</p>
