Bummer! You didn't copy `messy_list` to make `clean_list`. But I did!!!
So I did what I was told to do and it keeps telling me that I did not? Or am I wrong?
messy_list = [5, 2, 1, 3, 4, 7, 8, 0, 9, -1] # Your code goes below here clean_list = messy_list clean_list.sort()

[:] at the end. Otherwise they'll point at the same object.
