  ### Input:
  [3, 8, 6, 10, 17]
  
  ### Output:
  def odd_numbers_list(numbers):
      return [num for num in numbers if num % 2 != 0]
  assert odd_numbers_list([3, 8, 6, 10, 17])==[3, 17]
  assert odd_numbers_list([2, 4, 6, 8, 10])==[]
  assert odd_numbers_list([])==[]
  assert odd_numbers_list([1, 3, 5, 7, 9])==[1, 3, 5, 7, 9]
output: def odd_numbers_list(numbers):
      return [num for num in numbers if num % 2 != 0]
