Which method adds a new item to the end of a list?

• A. add()
• B. append()
• C. insert()
• D. push()

Answer: (B)

The method that adds a new item to the end of a list is the append() method. When you use append(), you are modifying the list in place by adding a single item at the very end of the existing elements. This is a common operation when working with lists in Python, as it allows for dynamic list expansion as new data is introduced. The append() method takes one argument, the item to be added, and it effectively increases the size of the list by one each time it is called. For example, if you have a list called `my_list`, executing `my_list.append(5)` would add the number 5 to the end of `my_list`. Other methods mentioned do not function in the same way. The add() method is not a built-in method for lists in Python. The insert() method allows you to add an item at a specific index, which is different from adding it to the end of the list. The push() term is used in other programming contexts, such as stacks, but it is not a built-in method in Python for lists. Therefore, append() is the correct choice for adding an item to the end of a list.
