title: Where can the __bytes__ method be found?
body: <p>The official documentation says:</p>
  
  <blockquote>
    <p><code>object.__bytes__(self)</code> </p>
    
    <p>Called by <code>bytes</code> to compute a byte-string
    representation of an object. This should return a <code>bytes</code> object.</p>
  </blockquote>
  
  <p>But when I do <code>dir(object)</code> or <code>dir(bytes)</code> or <code>dir(bytearray)</code>, the <code>__bytes__</code> method does not show up. So where can it be found? </p>
