You are SO close!! You need to inherit from list not "List".

Thank you! But what about the standard of writing classes beginning with a capital letter? if list is the parent class isnt it supposed to then be List instead?

In short, yes, it should be List but the original built-in types (list, str, dict) pre-date the PEP 8 naming standards.
