input: Write a function in Python that takes a list of integers and returns a new list containing only odd numbers.
  
  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]) == []
  assert odd_numbers_list([1, 3, 5, 7]) == [1, 3, 5, 7]
  assert odd_numbers_list([]) == []
  assert odd_numbers_list([7, 2, 9, 4, 11]) == [7, 9, 11]
output: def odd_numbers_list(numbers):
      return [num for num in numbers if num % 2 != 0]
