Python dataframe导出到excel中的市值

错误如下

for symbol in stock:
    try:
        sector = yf.Ticker(symbol).info['sector']
        name = yf.Ticker(symbol).info['shortName']
        cap = yf.Ticker(symbol).info['marketCap']
    except:
        sector = 'None'
        name = 'None'
    information[symbol,name,sector,cap] = web.get_data_yahoo(symbol, s,e)['Adj Close']
idx = pd.MultiIndex.from_tuples(information.columns)
information.columns = idx

我还可以将以下信息输入到excel的数据框中吗？是字符和数字的结果数据的差异导致不同的python语言产生上述错误吗

['language'，'region'，'quoteType'，'triggerable'，'quoteSourceName'， “货币”、“售前变更”、“售前变更百分比”， ‘上市前时间’、‘上市前价格’、‘定期市场变化’， “regularMarketChangePercent”、“regularMarketTime”、“regularMarketPrice”， “regularMarketDayHigh”、“regularMarketDayRange”、“regularMarketDayLow”， “regularMarketVolume”、“regularMarketPreviousClose”、“bid”、“ask”， “bidSize”、“askSize”、“fullExchangeName”、“financialCurrency”， “定期市场开放”，“平均每日交易量3个月”， “平均每日容积10天”、“52周以下变化”， “fiftyTwoWeekLowChangePercent”、“fiftyTwoWeekRange”， “fiftyTwoWeekHighChange”、“fiftyTwoWeekHighChangePercent”， “fiftyTwoWeekLow”、“fiftyTwoWeekHigh”、“dividendDate”， “earningsTimestamp”、“earningsTimestamp开始”、“earningsTimestamp结束”， “trailingannualdividentate”、“trailingPE”， “TrailingAnnualDividedield”、“marketState”、“EpstrailingTwevenmonths”， “epsForward”、“sharesOutstanding”、“bookValue”、“fiftyDayAverage”， “fiftyDayAverageChange”、“fiftyDayAverageChangePercent”， “TwoundredDayaAverage”、“TwoundredDayaAverageChange”， “百分之二百的平均变化率”、“市场上限”、“forwardPE”， “priceToBook”、“sourceInterval”、“exchangeDataDelayedBy”、“tradeable”， 'FirstTradeDateMills'、'priceHint'、'exchange'、'shortName'， 'longName'、'messageBoardId'、'exchangeTimezoneName'， “exchangeTimezoneShortName”、“GMTOFFSetName”、“market”， “esgPopulated”、“price”]

引发异常时，您尚未定义

cap='None'

。添加它会改善它吗？
