一、所需模块pandas_datareader的安装
(python2) [root@DL ~]# pip install pandas_datareader #用conda install panda_datareader提示找不到软件包，故改为pip install。
...
Installing collected packages: lxml, idna, chardet, urllib3, requests, pandas-datareader
Successfully installed chardet-3.0.4 idna-2.9 lxml-4.5.1 pandas-datareader-0.8.1 requests-2.24.0 urllib3-1.25.9
二、示例
import numpy as np
import pandas as pd
import pandas_datareader.data as web
import datetime
df_csvsave = web.DataReader("000858.SZ", "yahoo",datetime.datetime(2020,1,1),datetime.date.today())
#说明："000858.SZ"，若是上市股票，后缀为SS，深市股票（包括创业版、中小板），后缀为SZ。“yahoo”，表示从yahoo网获取数据来源。
print df_csvsave
结果：
High Low Open Close Volume Adj Close
