Question

我成功地从Quantl的WIKI交易所的股票代号MSCI的数据中获取数据，但是我无法从任何其他交易所市场（如LVMH，其股票代号为EURONEXT上的MC，根据this Quandl page）获得数据。确实，当我尝试使用以下命令实例化需要它的Stocker时：

class Stocker():

    # Initialization requires a ticker symbol
    def __init__(self, ticker, exchange='WIKI'):
        print("test")

        # Enforce capitalization
        ticker = ticker.upper()

        # Symbol is used for labeling plots
        self.symbol = ticker

        stock = quandl.get('%s/%s' % (exchange, ticker))

与msci = Stocker('MC',exchange='EURONEXT')

我收到一个KeyError：

KeyError                                  Traceback (most recent call last)

During handling of the above exception, another exception occurred:

如何从不同的交易所获取数量数据？
