如何處理 yfinance 中的“未找到”代碼？

Question

所以我試圖在一個循環中獲取一些股票數據（不確定我是否可以傳遞一個數組），如下所示：

def getData(ticker):
    print (ticker)
    data = pdr.get_data_yahoo(ticker, start=start_date, end=today)
    dataname= ticker+'_'+str(today)
    files.append(dataname)
    SaveData(data, dataname)

但是由於某些原因，找不到我提供給pdr.get_data_yahoo()的一些代碼，並且 python 會拋出此錯誤：

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/pandas_datareader/yahoo/daily.py", line 157, in _read_one_data
    data = j["context"]["dispatcher"]["stores"]["HistoricalPriceStore"]
KeyError: 'HistoricalPriceStore'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "borsdata_api.py", line 65, in <module>
    getData(row['ticker'])
  File "borsdata_api.py", line 47, in getData
    data = pdr.get_data_yahoo(ticker, start=start_date, end=today)
  File "/usr/local/lib/python3.7/site-packages/pandas_datareader/data.py", line 82, in get_data_yahoo
    return YahooDailyReader(*args, **kwargs).read()
  File "/usr/local/lib/python3.7/site-packages/pandas_datareader/base.py", line 251, in read
    df = self._read_one_data(self.url, params=self._get_params(self.symbols))
  File "/usr/local/lib/python3.7/site-packages/pandas_datareader/yahoo/daily.py", line 160, in _read_one_data
    raise RemoteDataError(msg.format(symbol, self.__class__.__name__))
pandas_datareader._utils.RemoteDataError: No data fetched for symbol ADDV-TO-1.ST using YahooDailyReader

是否可以跳過此迭代並繼續列表中的下一個迭代？

Answer 1

def getData(ticker):
    print (ticker)
    try:
        data = pdr.get_data_yahoo(ticker, start=start_date, end=today)
        dataname= ticker+'_'+str(today)
        files.append(dataname)
        SaveData(data, dataname)
    except:
        pass #or traceback.print_exc(), or traceback.format_exc()
        #print_exc() will raise the error and print traceback.
        #format_exc() will return the error as a string.
