title: Compute the sum of the positive numbers in a list in Python
body: <p>Studying for a test...this may be a question but I am stuck and can't figure out what I am doing wrong.</p>
  <pre class="lang-py prettyprint-override"><code>def theSum(aList):
      s = 0 
      for x in aList:
          if x &gt; 0:
              s+=x
      return theSum
  </code></pre>
