前言

前面撰文：【大麦小米学量化】通过pywencai访问同花顺问财接口实现智能选股
很多小伙伴应该已经用得很六了。但最近出了点小问题？解决后发出来，希望可以帮到大家。

一、pywencai 怎么了？

最近运行pywencai ，总是报错，同样的程序，怎么就报错了呢？

print后显示如下：

pywencai {'请填写主题': '<p>为你从5340只个股中找到<strong><span style="color:#ff2346">1644</span></strong>只符合条件的A 股，具体如下：</p>', 'xuangu_tableV1':      code  股票简称   最新价   最新涨跌幅  区间涨跌幅:前复权[19901220-20240104]  涨跌幅:前复权[20240110] market_code 交易状态[20240110]    股票代码

二、解决办法

通过增加各种筛选条件，过滤结果，总是不尽人意。突然想到，是不是该升级一下库了？

果然从0.12.0升级到0.12.2，再次运行以下选股代码，一切OK。

三、智能选股代码（缺环境的，请看开头文章推荐的博文）

# -*- coding: utf-8 -*-
import pywencai
def xg_wencai(query,perpage=200,ret='df'):
    # ret为code返回六位代码，symbol则为'代码.市场'格式，默认返回df
    df = pywencai.get(query=query, sort_key='股票代码', sort_order='asc', perpage=perpage, )
    if df is None:
        return None
    elif df.empty:
        return None
    else:
        if ret == 'symbol':
            return df['股票代码'].tolist()
        elif ret == 'code':
            return df['股票代码'].str[:6].tolist()
        else:
            return df.round(3)

if __name__ == '__main__':
    query = '非st；非停牌；连续3天涨幅介于1%-4%；股价大于60日均线；无长上影线；'
    fav_list = xg_wencai(query,perpage=200,ret='symbol')
    print(fav_list)

总结

以后库报错了，很有可能是系统有调整，先来一个 -U 升级一下。也许作者已经解决了，个人就别瞎折腾了。
