Flush's iWencai is a robot intelligent stock selection question and answer platform, input some conditional information to get the corresponding stock selection results.
从问财这个平台可以获得各式各样的选股数据，把这些数据融入到自己的股票量化交易平台中岂不是获得到了源源不断的数据源。Therefore, we integrated the QTYX interface into the stock quantitative analysis tool QTYX as one of the data sources, and combined with strategies and trading links, the system became more powerful and flexible. The stock quantitative analysis tool QTYX has been upgraded to version 2.6.4.
Preparation
First install iwencai's Python library wencai: pip install wencai
Since the js code is executed in the package, node.js needs to be installed to ensure that there is a js running environment locally.
After installing the library, do some configuration on the interface (this part has been completed in the SpecialData.py file of QTYX):
import wencai as wc
from wencai.core.session import Session
#i问财配置
Session.headers.update({'Host':'www.iwencai.com'})
wc.set_variable(cn_col=True)The data returned by the default wencai library is only the first page, so the source code of wencai needs to be modified.
In event.py and crawler.py, add a page number parameter page_size to the interface of the search function, and specify to obtain the data of a certain page. The specific changes are as follows:
The rest of the data cleaning and processing has been done in the SpecialData.py file of QTYX.
Disclaimer: Wencai introduced here is only for learning and research, and it is not recommended to obtain large-scale data.
