It need not be in-depth, merely illustrative of the problem being addressed. > I understand what you're asking though.

I think that the idiom for unused in xrange(10): # do stuff with no reference to 'unused' is quite common. Is that what you're asking about? > As far as I know, though, I think this is used often enough, so I > thought I'd just ask if there are purists out there who don't like > this use of the loop and feel it's an abuse of the syntax. No, it seems quite a normal usage of the syntax and a good use of an iterator. With "do something N times", there must be *something* to keep track of which iteration we're up to (or, equivalently, how many iterations remain) at a given moment. A Python iterator seems a fine choice to hold that information, and better than many alternatives. -- \ "My house is on the median strip of a highway.
