input: Write a function to filter out the odd numbers from a list of integers. The function should return a new list containing only the odd numbers from the original list. If the input list is empty, the function should return an empty list.
  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, 1, 1, 1])==[1, 1, 1, 1]
  assert filter_odd_numbers([])==[]
output: def filter_odd_numbers(lst):
      return [num for num in lst if num % 2 != 0]
