input: Write a function to filter out the odd numbers from a given list of integers. The function should return a list of odd numbers found in the input list.
  def filter_odd_numbers(numbers):
      filtered_list = []
      for num in numbers:
          if num % 2 != 0:
              filtered_list.append(num)
      return filtered_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, 3, 5, 7, 9])==[1, 3, 5, 7, 9]
  assert filter_odd_numbers([])==[]
output: def filter_odd_numbers(numbers):
      filtered_list = []
      for num in numbers:
          if num % 2 != 0:
              filtered_list.append(num)
      return filtered_list
