title: Check if all list values in dataframe column are the same
body: <p>I have a pandas dataframe with one of the column as a list:</p>
  <pre><code>df =
                          list_column
               0         [a b c d ...]
               1         [a b c d ...]
               2         [b a c d ...]
               ...        ...
  </code></pre>
  <p>How to check if list in all the rows for <code>list_column</code> are identical? In the above example, expected output is <code>False</code> because row 2 has a different list. Lists should be identical in the order in which the elements are present and not just merely the elements themselves.</p>
  <p>I tried the solution from <a href="https://stackoverflow.com/questions/54405704/check-if-all-values-in-dataframe-column-are-the-same">here</a>: It gives me an error:</p>
  <pre><code>AttributeError: 'bool' object has no attribute 'all'
  </code></pre>
