A) To insert an element at a specific position in the list
B) To remove the first occurrence of an element from the list
C) To add an element to the end of the list
D) To reverse the order of the elements in the list
- Which of the following is the correct way to access the last element of a list in Python?

B) list[0]
C) list[len(list)]
D) list[1]
- What is the main difference between a list and a tuple in Python?
A) A list is mutable while a tuple is immutable
B) A tuple is mutable while a list is immutable
C) A list can contain elements of different data types while a tuple can only contain elements of the same data type
D) A tuple can contain elements of different data types while a list can only contain elements of the same data type
Solution
-
The correct answer is C) To add an element to the end of the list. The append() method in Python is used to add an element to the end of the list.
-
The correct answer is A) list[-1]. In Python, you can use negative indexing to access elements from the end of the list. So, list[-1] will give you the last element of the list.
-
The correct answer is A) A list is mutable while a tuple is immutable. The main difference between a list and a tuple in Python is that lists are mutable (can be changed) while tuples are immutable (cannot be changed).
