我嘗試啟動(dòng)一個(gè)計(jì)時(shí)器來做一些文件歸檔工作。代碼是這樣的：from threading import Timermessage_archive_dir = "achivedir"message_archive_format = "zip"archive_timer = Timer(86400, messageachiver.archive, dir = message_archive_dir, fmt = message_archive_format)archive_timer.start()class messageachiver(object):    def __init__(self, **kwargs):            self.message_archive_dir = dir            self.message_archive_format = fmt    def archive(self):            print("message_archive_dir is " + self.message_archive_dir)            print("message_archive_format is " + self.message_archive_format)            print("Archiving trade messages")我收到以下錯(cuò)誤：Traceback (most recent call last):  File "sa_listener.py", line 43, in <module>    archive_timer = Timer(archive_interval, messageachiver.archive, dir = message_archive_dir, fmt = message_archive_format)TypeError: __init__() got an unexpected keyword argument 'dir'我不確定為什么 _ init _ 不接受 **kwargs。
