Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
[[7, -3, -3, 11], [-6, -6, -5, 2], [-8, 4, -3]]
Solution: [0, 72, -32]
Reason: 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.

Now, solve this instance: [[-43, 33, 43, 17], [-7, 46, 21, -26], [7, 34], [-16, 47, -22, -13, -3], [9, -2], [-37, 0], [15, -9, 43, 15, 19], [-37, -26, 29, 38], [16, 32, 20]]
Student:
[0, -1196, 34, 352, -2, 0, 0, -988, 10240]
