title: Function to find maximum of 3 variables isn't returning anything
body: <p>What is my problem? I run <code>biggest(10,5,6)</code> but it returns nothing.</p>
  
  <pre><code>def biggest(a,y,z):
      Max=a
      if y&gt;Max:
          Max=y
          if z&gt;Max:
              Max=z
              return Max
  </code></pre>
