Answer:
Nested lists __________ is a tool for building a new list from another list by applying an expression to each item in a sequence.
Step-by-step explanation:
The nested list can contain any sort object, even another list (sublist), which in turn can contain sublists themselves, and so on. Nested lists can be used to arrange data in hierarchical structures. Some nested lists are unordered lists, some are ordered lists, and others are description lists. The most important observation of a nested list is that it usually appears as an element on another list.
