我正在加载一个包含浮点数和字符串数据混合的txt文件.我想将它们存储在一个数组中,我可以访问每个元素.现在我正在做

import pandas as pd

data = pd.read_csv('output_list.txt', header = None)
print data

这是输入文件的结构:1 0 2000.0 70.2836942112 1347.28369421 /file_address.txt.

现在,数据将作为唯一列导入.我怎么能分开它,所以分别存储不同的元素(所以我可以调用data[i,j])？我该如何定义标题？

python版本是3.6.6，而pandas_datareader版本是0.7.0

当我导入pandas_datareader时，发生如下错误。

C:\PycharmProjects\Demo\venv\Scripts\python.exe C:/PycharmProjects/Demo/stock.py

    from pandas.compat import StringIO, bytes_to_str
ImportError: cannot import name 'StringIO'

有人可以帮我吗？
