We define `retval` as a tuple and then replace the tuple by "appending" items with `+=` but that actually creates a new tuple every time. Because it is intended to be mutable, use a list instead, then return a tuple from the function, as it should be immutable outside the function.

This is a really small semantic Python nit. Pinging @nodejs/python in case I'm just wrong in my understanding or something.
