通过baostock.com网站的股票数据获取方法

=====baostock.com==股票数据获取=====

import baostock as bs
import pandas as pd

#### 登陆系统 ####
lg = bs.login(user_id="anonymous", password="123456")


#### 获取历史K线数据 ####
# 详细指标参数，参见“历史行情指标参数”章节
rs = bs.query_history_k_data("sz.000001",
                             "date,code,open,high,low,close,preclose,volume,amount,adjustflag,turn,tradestatus,pctChg,peTTM,pbMRQ,psTTM,pcfNcfTTM,isST",
                             start_date='2000-06-01', end_date='2021-7-30',
                             frequency="d", adjustflag="3")  # frequency="d"取日k线，adjustflag="3"默认不复权
print('query_history_k_data respond error_code:' rs.error_code)
print('query_history_k_data respond  error_msg:' rs.error_msg)

#### 打印结果集 ####
data_list = []
while (rs.error_code == '0') & rs.next():
    # 获取一条记录，将记录合并在一起
    data_list.append(rs.get_row_data())
result = pd.DataFrame(data_list, columns=rs.fields)
#### 结果集输出到csv文件 ####
# result.to_csv("D:/history_k_data.csv", encoding="gbk", index=False)
print(result)
