Python Lists Methods

What is the output of the following list assignment

aList = [4, 8, 12, 16]

aList[1:4] = [20, 24, 28]

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]

  [30, 40, 50, 60, 70, 80]

• [30, 40, 50]

  [10, 20, 30, 40]

  [40, 50, 60, 70, 80]

• None of these

Select all the correct options to join two lists in Python

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

listTwo = ['e', 'f', 'g']

• newList = listOne + listTwo

• newList = extend(listOne, listTwo)

• newList = listOne.extend(listTwo)

• newList.extend(listOne, listTwo)

What is the output of the following

aList = [5, 10, 15, 25]

print(aList[::-2])

• [15, 10, 5]

• [10, 5]

• [25, 10]

What is the output of the following list function?

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

sampleList.append(60)

print(sampleList)

sampleList.append(60)

print(sampleList)

• [10, 20, 30, 40, 50, 60]

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

• [10, 20, 30, 40, 50, 60]

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

• both are wrong

In Python, list is mutable

• False

• True

Which of the following would give an error?

• list1=[]

• list1=[]*3

• list1=[2,8,7]

• None of the above

What will be the output of below Python code?

list1=[8,0,9,5]

print(list1[::-1])

• [5,9,0,8]

• [8,0,9]

• [8,0,9,5]

• [0,9,5]

Which of the following will give output as [23,2,9,75] ?

If list1=[6,23,3,2,0,9,8,75]

• print(list1[1:7:2])

• print(list1[0:7:2])

• print(list1[1:8:2])

• print(list1[0:8:2])

Suppose list1 is [1, 3, 2], What is list1 * 2 ?

• [2, 6, 4].

• [1, 3, 2, 1, 3]

• [1, 3, 2, 1, 3, 2]

• [1, 3, 2, 3, 2, 1]
