What method is used to add an item to a list in Python?

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

Answer: (B)

The method used to add an item to a list in Python is the append() method. This method effectively adds the specified element to the end of the list, modifying the existing list in place. For example, if you have a list called `my_list` and you want to add the element `5` to it, you would use `my_list.append(5)`. After this operation, `my_list` would contain the new element at the last position. The other methods listed are not suitable for adding elements to a list in the same way. The insert() method is used for adding an item at a specific position in the list rather than simply appending it to the end. The add() method does not exist for list objects, as it is typically associated with set objects. Lastly, push() is not a Python list method; it is commonly associated with stack implementations in various programming languages rather than standard list operations in Python.
