Scapy中的python回调语法错误

Question

我有下面的代码，我正在运行。获取python语法时出错。我在python2.7.10中使用Mac。有什么不对劲吗？我对python比较陌生

语法错误：语法无效 callback='parse_项'

完整代码：

    rules = [

        Rule(LinkExtractor(allow=[r'/7-august-2017/\w*'])
        callback='parse_item',
        follow = True)
    ]

    def parse_item(self, response):
        print response.url

您在19行的末尾忘了一个,：

        Rule(LinkExtractor(allow=[r'/7-august-2017/\w*']),
