title: Python word length function example needed
body: <p>I'm having a little bit of trouble with my homework.  I was supposed to write a function "limitWords" that restricts input to twenty words and truncates the input down to only 20 words if it's more than 20 words.  </p>
  
  <p>I used "len(text.split())" as a means to count up the words, so the 20 or less part works, but I don't know how to truncate the input without changing it into a twenty word list.</p>
  
  <p>I don't know if the way I did the first part of my if statement properly, but input on the second bit would be helpful.  I'm not looking for a copy and paste answer -- explanation or an example that's similar would be preferred.  Thanks!</p>
  
  <pre><code>totalwords = len(text.split())
  if totalwords &lt;= 20:
      return text
  </code></pre>
