Well yeah but that was what I was saying: in both cases (because there  
is no break) the `else:` clause has no purpose, the exact same  
behavior would be obtained by moving the code inside it to just behind  
the `for:` clause and removing the `else:` one. Therefore the "else:"  
part of the `else:` clause is noise in the system, it's not signal and  
it's not absent.
