Is your question about the semantics of for else blocks or about the 
suitability of the algorithm given in the example? The for else block 
is behaving exactly as expected...

>>> range(1,1)
[]
>>> range(500,500)
[]
>>>

for a good explanation of when the else part of the loop is executed. 
Basically, whenever the loop is exited normally, which is what happens 
when you iterate over an empty list like the one returned by 
range(1,1)
