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: [[-47, -29, -7, 31, -42], [-13, -41, -3, 35], [7, -31, -44], [20, 44, -39, 19, -9], [7, 24], [13, 1, -25, -38, 7], [31, 45, 48], [-45, -37, 18, 39, -32]]
Output:
[-42, 0, -44, 880, 24, -38, 48, -576]
