Under what possible circumstances would you prefer this code to the built-
in str.join method?

Particularly since the code isn't even correct, as it adds a spurious tab 
character at the beginning of the result string. 

(By the way, your solution, to call res.strip(), is incorrect, as it 
removes too much.)
