  assert filter_odd_numbers([1, 2, 3, 4, 5, 6]) == [1, 3, 5]
  assert filter_odd_numbers([2, 4, 6, 8]) == []
  assert filter_odd_numbers([1, 3, 5, 7, 9]) == [1, 3, 5, 7, 9]
  assert filter_odd_numbers([]) == []
output: def filter_odd_numbers(numbers):
      return [num for num in numbers if num % 2 != 0]
