Posted 2023-04-14

参考技术A pip install grpcio-tools

1、出现如下错误：

解决方案：pip install grpcio-tools -i https://pypi.doubanio.com/simple

后面的-i https://pypi.doubanio.com/simple即是镜像

python_库学习_01

一。python的库学习之

财经数据接口包

1.安装ThShare 直接pip install tushare

可能会出现缺少依赖库的情况，依次安装，大概有lxml,pandas,bs4,requests,pandas依次安装后查看tushare官方文档详细接口的使用

1. 查看是否安装成功查询版本号，

 

import tushare as ts

print ts.__version__，

3.ps 此库并不是在pythoncharm中运行，atom中或者cmd可以输出需要的数据

 

4..说明尝试

import tushare as ts

df = ts.get_hist_data(‘600848‘)

ts.get_hist_data(‘600848‘，ktype=‘W‘) #获取周k线数据

ts.get_hist_data(‘600848‘，ktype=‘M‘) #获取月k线数据

ts.get_hist_data(‘600848‘，ktype=‘5‘) #获取5分钟k线数据

ts.get_hist_data(‘600848‘，ktype=‘15‘) #获取15分钟k线数据

ts.get_hist_data(‘600848‘，ktype=‘30‘) #获取30分钟k线数据

ts.get_hist_data(‘600848‘，ktype=‘60‘) #获取60分钟k线数据

ts.get_hist_data(‘sh‘）#获取上证指数k线数据，其它参数与个股一致，下同

ts.get_hist_data(‘sz‘）#获取深圳成指k线数据 ts.get_hist_data(‘hs300‘）#获取沪深300指数k线数据

ts.get_hist_data(‘sz50‘）#获取上证50指数k线数据

ts.get_hist_data(‘zxb‘）#获取中小板指数k线数据

ts.get_hist_data(‘cyb‘）#获取创业板指数k线数据

Python财经数据接口包TuShare的使用

获取历史分笔数据

df = ts.get_tick_data(‘000756‘,‘2015-03-27‘)

df.head(10)

4.
