Solve the following python programming problem given the following code:
def _recursive_repr(fillvalue = '...') : 
    '
            Decorator to make a repr function return fillvalue for a recursive
            call
            ' 
    def decorating_function(user_function) : 
        repr_running = set () 
        def wrapper(self) : 
            key = (id (self), get_ident ()) 
            if (key in repr_running) : 
                return fillvalue 
repr_running.add (key) 
            try : 
                result = user_function (self) 
finally : 
                repr_running.discard (key) 
return result 
wrapper.__module__ = getattr (user_function, '__module__') 
        wrapper.__doc__ = getattr (user_function, '__doc__') 
        wrapper.__name__ = getattr (user_function, '__name__') 
        wrapper.__annotations__ = getattr (user_function, '__annotations__', {

        return wrapper 
return fillvalue
