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?

lists.py
messy_list = [5, 2, 1, 3, 4, 7, 8, 0, 9, -1]

# Your code goes below here
clean_list = messy_list
clean_list.sort()

To make a copy add [:] at the end. Otherwise they'll point at the same object.
