Write a function sum_of_rows_columns in a Python file named 1ab12_p2.py that takes a 2D list as a parameter and then returns a tuple containing two lists, the first list containing the sum of each row and the second list containing the sum of each column. Here is an example: >>>sum_of_rows_columns (1[1,2,3], [4,5,6], [7, 8, 911) ([6, 15, 24), [12, 15, 18])
