title: how to add new raw to the data frame during a loop and a certain condition is met?
body: <p>i want to add a new row when the iteration reach the raw which has 'total charges'.
  FYI: as shown in code, column number 1 is where it has to be performed.</p>
  <pre><code>python
  for row in df.itertuples():
      row[1] == 'Total Charges'
  </code></pre>
  <p><a href="https://i.stack.imgur.com/Alw4r.png" rel="nofollow noreferrer">this is how the data look like, i need to separate it with a row, right under total charges  </a></p>
