jqdata在提供基础数据的时候，并没有提供换手率这一数据，需要自己进行计算，本文将从财务数据里面计算出来换手率这一数据，合并到日数据和30分钟数据。

话不多说，直接上代码：

import pandas as pd
import jqdatasdk as JQ


stock_data_day_file = './data/day/'
stock_data_m30_file = './data/m30/'



# 获取日数据基本数据和财务数据
def get_day_data(stock,start_date,end_date):

    # 获取基本数据 =======================================================

                                 'pre_close', 'factor', 'paused'], fq='post').dropna()

    # 股票数据小于100条的丢弃
    if stock_pd.shape[0] < 100:
        return None,pd.DataFrame({})

    stock_pd = stock_pd.reset_index()  # 去掉索引，把日期索引转化为列

    # 处理日期格式
    stock_pd['date'] = pd.to_datetime(stock_pd['index'].values).strftime(date_format='%Y%m%d')
    stock_pd['date'] = stock_pd['date'].astype(int)

    # 处理代码格式
    stock_pd['code'] = stock.split('.')[0]
    stock_pd['code'] = stock_pd['code'].astype(int)

    # 处理成交量为前复权成交量
    stock_pd['volume_fq'] = stock_pd['volume']
    stock_pd['volume'] = stock_pd['volume'] * stock_pd['factor'] / 100   #  /100 股转为手

    # 成交额单位转换 元转换为千元 money
    stock_pd['money'] = stock_pd['money'] / 1000

    # 计算涨跌幅
    stock_pd['pct_change'] = (stock_pd['close'] / stock_pd['pre_close'] - 1) * 100
