print(aList)

• [4, 20, 24, 28, 8, 12, 16]

• [4, 20, 24, 28]

What is the output of the following list operation

aList = [10, 20, 30, 40, 50, 60, 70, 80]

print(aList[2:5])

print(aList[:4])

print(aList[3:])

• [20, 30, 40, 50]

  [10, 20, 30, 40]

Select all the correct options to join two lists in Python

listOne = ['a', 'b', 'c', 'd']

• newList = listOne + listTwo

• newList = extend(listOne, listTwo)

• newList = listOne.extend(listTwo)

• newList.extend(listOne, listTwo)

What is the output of the following list function?

sampleList = [10, 20, 30, 40, 50]
