title: Create a set from a series in pandas
body: <p>I have a dataframe extracted from Kaggle's San Fransico Salaries: <a href="https://www.kaggle.com/kaggle/sf-salaries" rel="noreferrer">https://www.kaggle.com/kaggle/sf-salaries</a>
  and I wish to create a set of the values of a column, for instance 'Status'.</p>
  
  <p>This is what I have tried but it brings a list of all the records instead of the set (sf is how I name the data frame).</p>
  
  <pre><code>a=set(sf['Status'])
  print a
  </code></pre>
  
  <p>According to this webpage, this should work.
