Definition: In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.
Input: [[-39, 14, -50, -29, 35], [46, -34, 24], [10, 42, -26, -4], [-34, -33, 36, 20], [-17, 25, 26], [-9, -48]]
Output:
[-700, -37536, 43680, -24480, 26, -48]
