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: [[-16, 40, -12, -29], [-50, -49, -46, 16], [-15, -49, -23, 44, -45], [-41, 22, 13, -19, -40], [12, 29, 39], [-47, -41], [-48, -43, -27, -34]]
Output:
[7680, 36800, 44, -880, 12, 0, 1632]
