I'd like to set up my code, so that only 1 blank space is remaining (I'll settle for none at this point), an the text wraps up to 100 chars or so out per line. Does anyone have any thoughts on the attached code? And what I'm not doing correctly?

I think this is a reasonable thing to do, but an awkward way to spell
it. If you mean to call the original wrap method, it would normally be
spelled super().wrap(para) instead.

Is that what you were intending, Steve?
