SyntaxError: multiple exception types must be parenthesized

[konrad]

Hello, I am trying to run this sample code to connect backtrader to IB and do live trading. I am unable to resolve this error:

SyntaxError: multiple exception types must be parenthesized

Any solutions to this problem are appreciated.
My code is attached.
Thanks!

import backtrader as bt

class MyStrategy(bt.Strategy):

    def __init__(self):
        print("initializing strategy")
        self.data_ready = False
        
    def notify_data(self, data, status):
        print('Data Status =>', data._getstatusname(status))
        if status == data.LIVE:
            self.data_ready = True

    def log_data(self):
        ohlcv = []
        ohlcv.append(str(self.data.datetime.datetime()))
        ohlcv.append(str(self.data.open[0]))
        ohlcv.append(str(self.data.high[0]))
        ohlcv.append(str(self.data.low[0]))
        ohlcv.append(str(self.data.close[0]))
        ohlcv.append(str(self.data.volume[0]))
        print(",".join(ohlcv))
    
    def next(self):
        self.log_data()

        if not self.data_ready:
            return

        # if not self.position:
        #     self.buy(size=2)
        # elif self.position:
        #     self.sell()

def start():
    print("starting backtrader")
    cerebro = bt.Cerebro()

    ##### For live trading #####
    # Can check port number by going into TWS and clicking file --> global configuration --> API --> settings
    # put in clientID?
    store = bt.stores.IBStore(port=7497)

    # Forex
    data = store.getdata(dataname='USD.JPY', sectype='CASH', exchange='IDEALPRO', timeframe=bt.TimeFrame.Seconds)

    # Aggregates into 15 second bars
    cerebro.resampledata(data, timeframe=bt.TimeFrame.Seconds, compression=15)
    
    cerebro.broker = store.getbroker()
    cerebro.addstrategy(MyStrategy)
    cerebro.run()

start()
