You will be given a definition of a task first, then some input of the task.
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.

[[-27, 22, 34, -34], [48, 10], [-50, -25], [-47, 23, 32, 38, 2]]
Output:
[-25432, 480, -50, 2432]
