my code works, but I do not understand the sort function.
Why do you not put anything in the parentheses of sort? I thought it should be" sort(square_list) similar how you would use the len function... I do not understand the concept of when there is open parentheses or when you put something inside the parentheses etc.
start_list = [5, 3, 1, 2, 4] square_list =  # Your code here! for number in start_list: square_list.append(number**2) square_list.sort() print square_list
