python 里面类继承

Question

python 里面类继承
现在要继承

import pymongo
class MongodbPipeline(object):

    def __init__(self, mongodbHost, mongodbPort,mongodbName, mongondbCollection):
        self.mongodbHost = mongodbHost
        self.mongodbPort = mongodbPort
        self.mongodbName = mongodbName
        self.mongodbCollection = mongondbCollection

    def from_crawler(cls, crawler):
        return cls(mongodbHost=crawler.settings.get('MONGODB_HOST'), mongodbPort=crawler.settings.get('MONGODB_PORT'),
                   mongodbName=crawler.settings.get('XIAOMIQUAN_DBNAME'),
                   mongondbCollection=crawler.settings.get('XIAOMIQUAN_COLLECTION'))

    def open_spider(self, spider):
        self.client = pymongo.MongoClient(self.mongodbHost, self.mongodbPort)
        self.mongodb = self.Client[self.mongodbName]
        self.db = self.mongodb[self.mongondbCollection]

这三个方法，只是里面的 数据库的dbname 和dbcollection不一样，其他都一样，现在在子类里面如何继承者三个方法

在子类的初始化是这么写的

def __init__(self, mongodbHost, mongodbPort, mongodbName, mongondbCollection):
        super(XiaoMiQuanPipeline, self).__init__(mongodbHost, mongodbPort, mongodbName, mongondbCollection)
