Python 2.7 TypeError:\uuuu init\uuuuuu（）最多接受6个参数（给定7个）python 2.7

如果返回测试：

            poloData = self.conn.api_query("returnChartData",{"currencyPair":self.pair,"start":self.startTime,"end":self.endTime,"period":self.period})

            for datum in poloData:

                if (datum['open'] and datum['close'] and datum['high'] and datum['low']):

                    self.data.append(BotCandlestick(self.period,datum['open'],datum['close'],datum['high'],datum['low'],datum['weightedAverage']))

---

我该怎么补救呢？我是新来的

我想我回答了我自己的问题，self是一个论点，所以问题在于bot candlestick父类。我一把它拿出来就行了
