Which method would you use to add an item to the end of a list?

The method used to add an item to the end of a list in Python is indeed list.append(). This method takes a single argument, which is the item to be added, and it modifies the list in place by adding the new item at the last position.

For example, if you have a list called my_list and you want to add the number 4 to it, you would simply write my_list.append(4). After executing this, 4 will become the last element of my_list.

In contrast, the other methods mentioned do not serve this purpose. The list.add() method is not a valid method in Python lists. Likewise, list.push() is not used in Python; it is a method found in some other programming languages, typically for stack operations. The list.insert() method allows you to add an item at a specified position in the list, but it does not add to the end by default unless that position is equal to the length of the list. This makes list.append() the appropriate choice for adding elements specifically to the end of a list.
