  </code></pre>
  <p>I want to filter out rows that correspond to this list of dates</p>
  <pre><code>list =  [01/10/2020, 01/11/2020, 01/14/2020, 01/16/2020, 01/20/2020, 02/01/2020, 02/03/2020, 02/04/2020]
  </code></pre>
  <p>There are multiple times corresponding to days and I want to keep all of them and drop only the rows that are not in the list of dates.</p>
  <p>I am new to Python and have been struggling with this for quite some time, any help will be greatly appreciated. Thank you!</p>
