Question

我觉得我很亲密，但是我从列表中读取文件名时遇到了问题。有人可以查看下面的代码并出错并帮助我吗？看起来我在使用列表创建要打开的每个文件名时遇到问题。这是我第一次这样做，所以我有点不知所措。

import pandas as pd

col_names = ['Date','Time','Open','High','Low','Close','Volume','Split Factor','Earnings','Dividends']

SymbolList = []
read = pd.read_csv('/Users/steve/Documents/MATLAB/all_symbols.csv', header=None, delimiter=',')
SymbolList.append(read)

for x in SymbolList:
    ticker = x
    data = pd.read_csv('/Users/steve/Documents/MATLAB/SNP500 STOCKS 1 MIN DATA/table_' + str(ticker) + '.csv', 
                       header=None, names=col_names, parse_dates=[['Date', 'Time']])
    data['Date_Time'] = pd.to_datetime(data.Date_Time.astype(str),format='%Y%m%d %H%M')
    data = data.set_index('Date_Time')
    data_NormalTradingHours = data.between_time('9:30','16:00')
    data_daily = (data_NormalTradingHours.resample('D')
               .agg({'Open': 'first', 'High': 'max', 'Low': 'min', 'Close': 'last', 'Volume': 'sum'})).dropna()
    data_daily.to_csv('/Users/steve/Documents/MATLAB/SNP500 STOCKS 1 MIN DATA/' + str(ticker) + '_D.csv', sep=',')

这是错误：
