title: How to Display the MultiIndex object of a data frame?
body: <p>I had a DataFrame <code>jobs_2</code> which has many columns, amongst which are <code>city</code> and <code>state</code>.</p>
  
  <p>From <code>jobs_2</code> I created a new DataFrame <code>jobs_2i</code> where state and city are set as indices of <code>jobs_2</code>.</p>
  
  <p>For that I used the code:</p>
  
  <pre><code>jobs_2i = jobs_2.set_index(['state', 'city'])
  </code></pre>
  
  <p>I now need to use an appropriate property of data frames to display the MultiIndex object of <code>jobs_2i</code>, but I am unsure how to do that.</p>
