Question

what do you mean by nesting of list

Answer 1

A nested list is simply a list that occurs as an element of another list(which may of course itself be an element of another list, etc.). Common reasons nested listsarise are: They're matrices (a list of rows, where each row is itself a list, or a list of columns where each column is itself a list)

Answer 2

A list within a list is called a nested list.

This collection of lists is called a nested list
