Given the task definition, example input & output, solve the new input case.
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.
Example: [[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Output: [0, 72, -32]
The first inner list has no even integers, so the first number in the output is 0. The second list has -6, -6, 2 for even integers so the second output is 72. The third list has -8, 4 as even numbers so the third output is -32. This is a good example.

New input case for you: [[-20, -17, 34, -31, -4], [-38, 30, 33], [2, 32, 21, -27], [-23, -47, 35, -16], [-6, -35, 31], [-13, 48, -20], [49, 14, -29], [-15, -38, 3], [-31, -21, 34], [-23, -29, -31, 24], [-35, -4], [-17, 46], [-1, 33, 1, -44, 11], [2, -33, -13], [-8, 1]]
Output:
[2720, -1140, 64, -16, -6, -960, 14, -38, 34, 24, -4, 46, -44, 2, -8]
