  <p>I want to extract the data using latest date from the dataframe.
  I was using the following formula, but the output is different</p>
  <pre><code>df = df.Date.max()
  </code></pre>
  <p>Output: <code>2020-10-24 00:00:00</code>.</p>
  <p>The output which i am looking for is</p>
  <pre><code>Date           Sub  Value
  10/24/2020     A    1
  </code></pre>
