title: df.apply() but skip the first row
body: <p>I am trying to apply the following df.apply command to a dataframe but want it to skip the first row. Any advice on how to do that without setting the first row as the column headers?</p>
  <pre><code>res = sheet1[sheet1.apply(lambda row: row.astype(str).str.contains('TRUE', case=False).any(), axis=1)]
  </code></pre>
