Solve the following python programming problem given the following code:
def _setup_hidden_services(self, servicelines) : 
    def maybe_add_hidden_service() : 
        if (directory is not None) : 
            if (directory not in directories) : 
                directories.append (directory) 
                hs.append (HiddenService (self, directory, ports, auth, ver, group_read)) 
else : 
                raise RuntimeError (('Trying to add hidden service with same HiddenServiceDir: %s' % directory)) 
hs = [] 
    directory = None 
    directories = [] 
    ports = [] 
    ver = None 
    group_read = None 
    auth = None 
    for line in servicelines.split ('
') : 
        if (not len (line.strip ())) : 
            continue 
if (line == 'HiddenServiceOptions') : 
            continue 
(k, v) = line.split ('=') 
        if (k == 'HiddenServiceDir') : 
            maybe_add_hidden_service () 
            directory = v 
            _directory = directory 
            directory = os.path.abspath (directory) 
            if (directory != _directory) : 
                warnings.warn (('Directory path: %s changed to absolute path: %s' % (_directory, directory)), RuntimeWarning) 
ports = [] 
            ver = None 
            auth = [] 
            group_read = 0 
else : 
            if (k == 'HiddenServicePort') : 
                ports.append (v) 
else : 
                if (k == 'HiddenServiceVersion') : 
                    ver = int (v)

else : 
                            raise RuntimeError (("Can't parse HiddenServiceOptions: " + k)) 
maybe_add_hidden_service () 
    name = 'HiddenServices' 
    self.config [name] = _ListWrapper (hs, functools.partial (self.mark_unsaved, name))
