title: How to find the index number of second or third occurence of a word in a sentence, without using starting index or range as parameter? (python)
body: <p>I have the following sentence - </p>
  
  <pre><code>Sammy likes to swim in the ocean, likes to spin servers, and likes to smile.
  </code></pre>
  
  <p>I want to find the starting index number of the second occurrence of the word <code>likes</code></p>
  
  <p>But I don't want to use a starting index number or range as parameter of <code>str.find()</code> function.</p>
  
  <p>If possible I want to avoid regular expression as it is difficult to understand for starters.</p>
  
  <p>NOTE: It is not mandatory to use <code>str.find()</code> function. I just want to know whether it is possible without giving starting index or range as parameter.</p>
