Question

Quizplus · Accepted Answer

The assignment `List2 = list(list1)` creates a shallow copy of `list1`, meaning that while `List2` is a new list, the elements inside are still references to the same objects in memory as those in `list1`. Therefore, modifying an element in one of the sublists of `List2` (like setting `List2[0][0] = 10`) also modifies that element in `list1`, making `list1[0][0]` and `list2[0][0]` both equal to 10.
