TASK 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.
PROBLEM: [[-29, -40, -45, -11, 8], [-44, -42, -37, -7], [0, -12], [25, -48, -44, 14], [12, -44, 27], [13, -46, -27], [34, -20, 29]]

SOLUTION: [-320, 1848, 0, 29568, -528, -46, -680]
