body: <p>How to use a recursive function to count the sum of the positive elements of a list?</p>
  
  <p>I'm not sure how to go about it? I know how to do it without using a recursive function:</p>
  
  <pre><code>sum=0
  for i in range(len(List)):
      if List[i]&gt;0:
          sum=sum+List[i]
  </code></pre>
