Mastering Python List Operations

What will be the output of the following code: list1 = [1, 2, 3]; print(list1[0])?

• 1

• 3

• 0

• 2

How do you add an element '4' to the end of list1 = [1, 2, 3]?

• list1.insert(4)

• list1.add(4)

• list1.append(4)

• list1.extend(4)

What does the method list1.remove(2) do to the list list1 = [1, 2, 3]?

• The list becomes [1, 3].

• The list becomes [1].

• The list becomes [2, 3].

• The list becomes [1, 2, 3].

If list2 = [5, 6, 7] and you execute list1=list2, what will list1 contain?

• [5, 6, 7]

• [5, 6]

• [5, 6, 7, 8]

• [6, 7]

List1=[0,2,3] .What is the result of len(List)?

• [2, 3]

• 2

• 3

• [1, 2, 3]

How can you create a new list that is a copy of list1 = [1, 2, 3]?

• new_list = list1.extend([])

• new_list = list1.copy() or new_list = list1[:]

• new_list = list1.append(4)

• new_list = list1 + []

What will be the output of the following code: list1 = [1, 2, 3,7]; print(len(list1))?

• 2

• 4

• 3.5

• 3

If list1 = [1, 2, 3] and you execute list1[1]='a', what will list1 look like?

• [1, 2, 'a', 3]

• ['a', 1, 2, 3]

• [1, 'a', 2, 3]

• [1, 2, 3, 'a']

What does the method list1.sort() do to the list list1 = [3, 1, 2]?

• The list list1 becomes [1, 2, 3].

• The list list1 becomes [3, 2, 1].

• The list list1 remains unchanged.

• The list list1 becomes [2, 3, 1].

list1 = [1, 2, 3]
find the correct code to make the the list look like this:
list1=[2,3,4]

• list1.append(1)
  list1.remove(1)

• list1.append(4)
  list1.remove(1)

• list1.append(4)
  list1[0]=1
