title: Pandas Series unique method showing values looking the same
body: <p>I have a pandas dataframe. When I run the .unique() method to one of the columns, it shows values looking the same. How can I see how these values differ? I tried to index from the unique() method but the values were just the strings as shown below. Thanks for the help.</p>
  
  <pre><code>df["MyColumn"].unique()
  array(['yi̇', 'yd', 'yi'], dtype=object)
  _______________________________________
  df["MyColumn"].unique()[0]
  'yi̇'
  _______________________________________
  df["MyColumn"].unique()[2]
  'yi̇'
  
  </code></pre>
