input: Write a function to filter out the odd numbers from a given list. The function should iterate through the list and append only the odd numbers to a new list, which is then returned. The function should be named `filter_odd_numbers`.
  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])==[1, 3, 5, 7]
  assert filter_odd_numbers([10, 11, 12, 13, 14])==[11, 13]
  assert filter_odd_numbers([])==[]
output: def filter_odd_numbers(lst):
      return [num for num in lst if num % 2 != 0]
