Hmmm. I've never run into a case where the loop logic is that nasty. 
And,  as it turns out, even the above isn't that nasty if you stare at 
it a minute, it can be coded without break/exit at all. So this is how 
I'd code it <0.5 wink>:

n=4
for i in range(1,n):
     for k in range(1,i+2):
         print i, 1, k

Of course this just dodges your point, but I can't be made to care 
unless you convince me that I'm likely to run into something like this 
in practice.
