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: [[9, -25, -21, 12], [-33, -41, -2, -34, 14], [46, 43, 47, -42], [13, -14, -27, 1, -41], [34, -48, 36, 1], [34, -7, 1, 33, 32], [-20, -38, 6]]
Output:
[12, 952, -1932, -14, -58752, 1088, 4560]
