Stuck on lists and dictionaries, I keep getting this error and am not sure why. I looped, appended, and sorted as instructed.
Oops, try again. It looks like square_list has 2 at index 1 instead of 4.
start_list = [5, 3, 1, 2, 4] #list_name and items(variable) square_list =  for x in start_list: #for variable in list_name print x ** 2 square_list.append(x) square_list.sort() print square_list
