Final contents of `myList` after the following operations: myList = [80, 70] myList.append(60) myList.extend([50, 40])

Answer explanation

Starting with myList = [80, 70], we append 60, resulting in [80, 70, 60]. Then, we extend it with [50, 40], giving us [80, 70, 60, 50, 40]. Thus, the final contents of myList are [80, 70, 60, 50, 40].

Debug the code to print list elements on separate lines: a = ['usha', 'lata', 'ayesha'] for i in range(len(a)): print(i)

Answer explanation

To print list elements on separate lines, change 'print(i)' to 'print(a[i])'. This will print the actual elements of the list 'a' instead of their indices.

Analyze the list `A = [50, 0, 1, 8, 0, 0, 2, 0, 2, 0, 58, 106, 20]`: a) Find the length of the list b) The value of `A[-1]` c) The result of `A[::2]` d) The result of `A[4:8]`

Answer explanation

a) Length of A is 13. b) A[-1] is 20, the last element. c) A[::2] gives [50, 1, 0, 2, 58, 20], elements at even indices. d) A[4:8] results in [0, 0, 2, 0], elements from index 4 to 7.

What will be the output of the following code? my_list = [1, 2, 3, 4] my_list.append([5, 6]) print(len(my_list))
