Question

Explain Nested lists.

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 lists arise 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 alist)

Answer 2

Answer:

A nested list is a list within another list. Elements of a nested list can be accessed by integer indexing.

Eg:

list1 = [1, 2, 3, [4, 5], 6]

print(list1[3])

o/p

[4,5]
