This is my exact course I'm stuck on:
It says, "Make sure not to modify start_list!" But I don't get how I'm modifying it.
Also, when it prints to the console, it prints out "1, 4, 9, 16, 25" so I got it to print the correct numbers, but there's still an error message. Can someone help me??
start_list = [5, 3, 1, 2, 4] square_list =  # Your code here! for start_list in start_list: square_list.append(x**2) square_list.sort() print square_list
