input: Write a python function to get odd numbers from a list.
  assert get_odd_numbers([1, 2, 3, 4, 5, 6, 7, 8, 9]) == [1, 3, 5, 7, 9]
  assert get_odd_numbers([10, 15, 20, 25, 30]) == [15, 25]
  assert get_odd_numbers([0, 2, 4, 6, 8, 10]) == []
output: def get_odd_numbers(lst):
      return [num for num in lst if num % 2 != 0]
