 - In the second example, list `iter1` is updated using slice assignment. Slice assignment, in contrast to normal assignment(which creates a new list), updates the same list. We can view this as the slice of list being replace by the iterable on right hand side of equality. Hence, the generator `g2` yields updated `iter2` elements.
