title: Create a row for each record separated by some pattern
body: <p>I need to create a row in the pandas dataframe for each record in the <code>&quot;ativos&quot;</code> column and the other data (<code>&quot;nome&quot;</code>) must be repeated. Records are separated by this string <code>&quot;\r\n&quot;</code> in the <code>&quot;ativos&quot;</code> column. However, I don't know how to do it correctly.</p>
  <pre><code>   nome            activos
  0  Luiz  ABC\r\nDEF\r\nGHI
  </code></pre>
  <p>Expected result:</p>
  <pre><code>   nome activos
  0  Luiz     ABC
  1  Luiz     DEF
  2  Luiz     GHI
  </code></pre>
