  <p>Following question is about python codestyle and may be design of reusable lib. So I have <a href="http://en.wikipedia.org/wiki/Builder_pattern" rel="nofollow noreferrer">builder</a> that chains graph creation into single big line as follow:</p>
  
  <pre><code>graph.builder() \
          .push(root) \
          .push(n1) \
          .arc(arcType) \ #root-arc-n1 error is there
          .push(n2) \
  ...
  </code></pre>
  
  <p>At line #4 I get the error about wrong symbol (#). So general question how to produce well commented code against long builder path. Also as a good answer I'll appreciate suggestion on changes in builder to allow comments for clarifying code. </p>
