title: python encode()
body: <p>Has hex codec been excluded from python 3.3? When I write the code</p>
  
  <pre><code>&gt;&gt;&gt; s="Hallo"
  &gt;&gt;&gt; s.encode('hex')
  Traceback (most recent call last):
    File "&lt;pyshell#24&gt;", line 1, in &lt;module&gt;
      s.encode('hex')
  LookupError: unknown encoding: hex
  </code></pre>
  
  <p>What does that mean? I know about binascii.hexlify() but still .encode() method is nice!
  Any suggestion?</p>
