Like in most of the cases I played with generators, you could have replaced
them with a simple s = "" at the beginning, replace every yield with s +=
<whatever> and a return s at the end. I think you can always do this if all you
want is a list.

I like them, too :-)

>(Probably Python should use "black bullet" or "*" instead of "yield":

I prefer "yield".
