input: Write a function to optimize the given Python program that prints each element of a list on a new line. Consider using list unpacking and the `sep` parameter of the `print` function to achieve this. If the given list is empty, the program should simply return without any output.

      if not numbers:
          return
      print(*numbers, sep='\n')
