IMPORTANT: A `Traversal` is essentially an `Iterator` so if you have code like `x = g.V()`, the `x` does not contain
the results of the `g.V()` query. Rather, that statement assigns an `Iterator` value to `x`. To get your results,
you would then need to iterate through `x`. This understanding is *important* because in the context of the console
