我有一个pandas read_csv的问题.我有很多与股票市场相关联的txt文件.它是这样的:

我用这段代码来读它:

fields = ['SecCode', 'Tdate','Ttime','LastClose','OP','CP','Rf1','Rf2']  
df = pd.read_csv('SHL1_TAQ_600000_201201.txt',usecols=fields)

但是我遇到了一个问题:

Traceback (most recent call last):
  File "E:/workspace/Senti/highlevel/highlevel.py", line 8, in <module>
    df = pd.read_csv('SHL1_TAQ_600000_201201.txt',usecols=fields,header=1)
  File "D:\Anaconda2\lib\site-packages\pandas\io\parsers.py", line 562, in parser_f
    return _read(filepath_or_buffer, kwds)
  File "D:\Anaconda2\lib\site-packages\pandas\io\parsers.py", line 315, in _read
    parser = TextFileReader(filepath_or_buffer, **kwds)
  File "D:\Anaconda2\lib\site-packages\pandas\io\parsers.py", line 645, in __init__
    self._make_engine(self.engine)

    self._engine = CParserWrapper(self.f, **self.options)

    raise ValueError("Usecols …

如图所示,如何在pandas数据帧中为索引添加名称？添加时应如下所示:
