title: Search strings behind an index
body: <p>I work with a list (<code>lst_data</code>) containing paths to the data.</p>
  
  <p>Here's an example from my list</p>
  
  <pre><code>lst_data = ["SDE_AGS_ADM.PLUVIOMETRIE \ SDE_AGS_ADM.Pluviometres_DAVAR",
              "SDE_AGS_ADM.AIRE_PROTEGE_GOUV \ SDE_AGS_ADM.reserves_integrales_R",
              "SDE_AGS_ADM.DGRSC_Lignes_feu"]
  </code></pre>
  
  <p>Let's look at this list.</p>
  
  <p>The first element contains 2 ".", the second element also contains 2 ".", but the third element contains only one ".".</p>
  
  <p>I try to get the characters after the last "." each element of the list.</p>
  
  <p>Can anyone help me?</p>
  
  <p>I already try using the <code>count ()</code> function. But I'm confused :-)</p>
  
  <p>thank you</p>
