title: Python/Pandas return column and row index of found string
body: <p>I've searched previous answers relating to this but those answers seem to utilize numpy because the array contains numbers. I am trying to search for a keyword in a sentence in a dataframe ('Timeframe') where the full sentence is 'Timeframe for wave in ____' and would like to return the column and row index. For example:</p>
  
  <pre><code>    df.iloc[34,0] 
  </code></pre>
  
  <p>returns the string I am looking for but I am avoiding a hard code for dynamic reasons. Is there a way to return the [34,0] when I search the dataframe for the keyword 'Timeframe'</p>
