title: How to cube a number
body: <p>I just started using Python today for my class and one of my problems is cubing a number in Python. I know the way to do it is <code>x^3</code>, but that doesn't work in Python. I was just wondering how I would be able to do that. </p>
  
  <p>This is what I tried so far, but as you can see, I keep getting syntax errors:</p>
  
  <pre><code>&gt;&gt;&gt; def volume (v) :
      return v^3
  volume(4)
  SyntaxError: invalid syntax
  </code></pre>
