Funny, I started typing a comment here, about the author not getting the Ruby side of things right, that actually the difference would rather be that Ruby uses a special language construct and Python just normal methods and conventions. But just skimming through the previous comments it seems that Python also has these a `yield` keyword that would be more idiomatic to use.

I think we're dealing with someone who had limited experience with both Python and Ruby. This article is somehow getting more attention then it merits.
