  assert filter_evennumbers([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) == [2, 4, 6, 8, 10]
  assert filter_evennumbers([10, 20, 45, 67, 84, 93]) == [10, 20, 84]
  assert filter_evennumbers([5, 7, 9, 8, 6, 4, 3]) == [8, 6, 4]
output: def filter_evennumbers(numbers):
      return [num for num in numbers if num % 2 == 0]
