Solve the following python programming problem given the following code:
def decorator(wrapped_decorator) : 
    "Converts a function into a decorator that optionally accepts keyword
  arguments in its declaration.

  Example usage:
    @utils.decorator
    def decorator(func, args, kwds, op1=None):
      ... apply op1 ...
      return func(*args, **kwds)

    # Form (1), vanilla
    @decorator
    foo(...)
      ...

    # Form (2), with options
    @decorator(op1=5)
    foo(...)
      ...

  Args:
    wrapped_decorator: A function that accepts positional args (func, args,
      kwds) and any additional supported keyword arguments.

  Returns:
    A decorator with an additional 'wrapped_decorator' property that is set to
  the original function.
  " 
    def helper(_func = None, **options) : 
        def outer_wrapper(func) : 
            @ wrapping (func) 
            def inner_wrapper(* args, **kwds) : 
                return wrapped_decorator (func, args, kwds, ** options) 
return inner_wrapper 
if (_func is None) : 
            return outer_wrapper 
if options : 
            raise TypeError ('positional arguments not supported') 
return outer_wrapper (_func) 
helper.wrapped_decorator = helper 
    return helper 

    
    

    Fix the buggy line: helper.wrapped_decorator = helper
assistant
#Here is Python code to fix the buggy line: helper.

helper.wrapped_decorator = wrapped_decorator
