• It can only be applied to tuples, not lists

• It creates a new list containing a subset of elements from the original list

• It modifies the original list in place

• It is used to reverse the order of elements in a list

What is the result of the following code snippet? my_list = [1, 2, 3, 4, 5] my_list[1:3] = [6, 7, 8] print(my_list)

• [1, 6, 7, 8, 4, 5]

• [1, 2, 6, 7, 8, 4, 5]

• [1, 2, 3, 6, 7, 8, 4, 5]

• [1, 2, 6, 7, 8, 5]

Which method is used to remove the last element from a list in Python?

• `remove()`

• `delete()`

• `pop()`

• `discard()`
