title: comma after every element in list instead of the last one
body: <p>I want to make a function which would add comma after every word in list instead of the last one. I tried to do it with a while-loop so it could stop before the comma reaches the last word, but the output of the code is not doing its job.</p>
  <pre><code>list = ['Sadzo', 'Nimadaro', 'Duol']
  wordIndex = 0
  LenghtUnderIndex = len(list[wordIndex])
  
  while wordIndex &lt;= len(list):
    list.insert(LenghtUnderIndex, ', ')
    wordIndex += 1
    break
  
  print (*list)
  </code></pre>
