Doesn't always need a tuple, but does need a tuple if the parameter to be converted is already a tuple. So the tuple isn't exactly gratuitous. In fact in a way it makes your code more polymorphic, which is said to bring good luck. When you're sure that the expression that appears there on the right hand side of % is not and will never be a tuple, then the (a,) one-tuple is unnecessary. If you aren't sure, it _is_ necessary.
