Hi, What did you mean here? Write a function to determine whether all numbers in a list are unique. do we need to explicitly say which one is unique or we just need to identify if all of them are unique? Here is a sample of my solution: def unique(list1): uni='Not Unique' unique_list = [] for x in list1: if x not in unique_list: unique_list.append(x) if len(list1) == len(unique_list): uni= 'Unique' return uni list1 = [10, 20, 30, 40] unique(list1) Best, Christian

Hey Christian, Thank you for your question! The task is to determine whether all numbers are unique, there is no need to identify the unique numbers themselves. I think your solution is great and solves the task as expected. You can also study Giles' solution for an alternative approach :) Kind regards, 365 Hristina

Hi Hristina, Where can I find Giles' solution so I can see an alternative approach? Thank you. Best, Christian
