How can you append an item to a list in Python?

In Python, the append() method is specifically designed for adding a single item to the end of a list. When this method is called, it takes the item you want to add as an argument and modifies the list in place, effectively increasing its length by one.

For example, if you have a list called my_list and you want to add the string "apple" to it, you simply use the syntax my_list.append("apple"). This is straightforward and efficient, making append() the appropriate choice when you need to add one item.

The other methods may have functionalities related to lists but don't serve the same purpose as append(). The add() method is not applicable to lists; it's typically associated with sets. The insert() method would allow you to add an item at a specified position within the list, which is different from appending. Lastly, the extend() method can be used to add multiple items to the end of the list by merging another iterable (like another list) with it, but it does not add a single item as append() does.
