Question 25: Find the output of the following program:
def REVERSE(L): L.reverse() return(L) def YKNJS(L): List = [] List.extend(REVERSE(L)) print(List) L = [1, 3.1, 5.31, 7.531] YKNJS(L) |
(A) [1, 3.1, 5.31, 7.531]
(B) [7.531, 5.31, 3.1, 1]
(C) IndexError
(D) AttributeError: ‘NoneType’ object has no attribute ‘REVERSE’
Answer: (B)
Explanation: REVERSE() reverses the list and returns it. YKNJS() adds reverse of a list L to the empty list List. L = [1, 3.1, 5.31, 7.531], gets reversed and becomes [7.531, 5.31, 3.1, 1].
