I used it primarily because it mirrored my thinking; I don't know what
that says about me!  That's how I've often implemented the trinary 
operator.  I would have used 

   sign = '-' if n<0 else ''

But I'm still on Python 2.4.  I guess

   sign = (n<0) and '-' or ''

is the pre-2.5 idiom, but I find that even less clear.
