I don't see why you're trying to draw that analogy, since a loop has 
nothing in common with a try block. For the record, when I was a Python 
beginner, I had zero problem understanding the for/else construct, and 
it even struck me as very useful ("oh, they've thought about a clean and 
easy way to write search-and-break loops").

I don't think it's useful to think of beginners as people having 
comprehension problems. Besides, if you don't understand something up 
front, there's always the possibility to come back later.
