Answer

After performing the provided operations on myList, the changes will be as follows:

  1. myList.append([50,60])

    • The append method will add [50, 60] as a single element (nested list) at the end of myList.

    • Result: myList = [10, 20, 30, 40, [50, 60]]

  2. myList.extend([80, 90])

    • The extend method will add each element of [80, 90] individually to the end of myList.

    • Result: myList = [10, 20, 30, 40, [50, 60], 80, 90]

So, the final elements of myList after both operations will be:

[10, 20, 30, 40, [50, 60], 80, 90]
