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: [[-34, -38, -13], [-41, 27, -17, -33], [31, 6], [-35, 25, -46, -26], [40, 21, 9, 34, 43], [34, 39, 2, 35], [36, -7, 0, -45], [45, 38, 40], [-46, 28, -15, -34], [40, -50, 27], [20, 20, 41]]
