How to return a list of a list in python?

Question

Assume I input list containing [1,2,3,4]. How do I make it so it returns another list only containing the first and last entry ([1,4]).

That's not a list of lists - that's a list containing only part of the original list. — EJoshuaS - Stand with Ukraine, Oct 16 '20 at 15:02

To returns another list only containing the first and last entry you may

    a=[1,2,3,4]
    b=[a[0], a[-1]]
    b
    [1, 4]
