What are some examples of sets and lists in Python?

In Python, a list is an ordered collection of items, while a set is an unordered collection of unique items. For example, a list can be defined as my_list = [1, 2, 3, 4] and a set as my_set = {1, 2, 3, 4}.

Can you show me how to add items to a list and a set?

Sure! To add an item to a list, you can use the append() method, like this: my_list.append(5). For a set, you can use the add() method: my_set.add(5).

What happens if I add a duplicate item to a set?

If you add a duplicate item to a set, it will not be added again, as sets only store unique items. For example, if you do my_set.add(3), the set will remain unchanged.

How do I remove items from a list and a set?

To remove an item from a list, you can use the remove() method, like this: my_list.remove(2). For a set, you can use the discard() method: my_set.discard(2), which won't raise an error if the item is not found.
