[Chicago] Can this be done with a yield statement and generator object?

[Lewit, Douglas]

Hey guys,

I'm attaching a simple class that I created in Python.... Python 3 to be
specific, but I think it should work in Python 2 as well, maybe.  Anyhow,
is there a way to implement the same concept using a *yield statement* in a
function to create a generator object?  Just wondering.  Let me know,
thanks!

Best,

Douglas Lewit

P.S.  Obviously if you use a generator object to do this then the generator
object would never produce the StopIteration error.  But I'm kind of
confused about how to create and define a generator object that would
produce this cyclical behavior in an array or list.
