Part 1. 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.
Part 2. Example
[[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Answer: [0, 72, -32]
Explanation: 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.
Part 3. Exercise
[[-29, -15, -2], [-25, -35, 26, 27], [3, -27], [-36, 40, 30], [-25, 37], [28, 37, -36], [14, -4, 33, -16, -42]]
Answer:
[-2, 26, 0, -43200, 0, -1008, -37632]
