Without any importing? Yes, that is what one *should* do in late 2.x and indeed must do in 3.x, where the string module has been stripped of the functions that later became string methods. The FAQ entry was written when the join method was new as a method and some people were upset by the reversal of the order of the two arguments, an iterable of strings and the joining string. -- Terry Jan Reedy
