25. What is the difference between list.append(item) and list.extend(iterable)?

append() adds an item to the end, extend() adds multiple items as a single element.

append() adds a single item, extend() adds all items from an iterable.

append() modifies the original list, extend() returns a new list.

append() is faster for large datasets, extend() is slower.
