Question

Consider the following list myList. What will be the elements of myList after the following two operations:
myList = [10,20,30,40]
i. myList.append([50,60])
ii. myList.extend([80,90])

Answer 1

i) append() function takes only one argument and inserts the element to the end of the list. Here, the argument is a list containing the element 50, 60. Therefore, the output will be: [10, 20, 30, 40, [50, 60]]

ii) extend() function takes a list as an argument and appends each element of the list in the same order. The final output will be: [10, 20, 30, 40, [50, 60],80,90]
