原生python获取通达信沪深300成分股

速度快，好用，36.137.190.158地址换成你通达信登录界面，通讯设置的行情服务器IP地址
def get_hs300s():
    from pytdx.hq import TdxHq_API
    from pytdx.params import TDXParams
    # 创建API对象
    api = TdxHq_API()
    # 连接到通达信服务器
    if api.connect('36.137.190.158', 7709):
        print("连接成功")
        # 获取板块成分股
        stock_list = api.get_and_parse_block_info(TDXParams.BLOCK_SZ)
        # 提取股票代码并存储到列表中
        stock_codes = [stock['code'] for stock in stock_list if stock['blockname'] == '沪深300']
        # 对股票代码添加后缀
        stock_codes_with_suffix = [
            f"{code}.SH" if code.startswith('6') else f"{code}.SZ"
            for code in stock_codes
        ]
        # 断开连接
        api.disconnect()
    else:
        print("连接失败")
    return stock_codes_with_suffix

xtquant更简单，直接
stock_dict300=xtdata.get_index_weight('000300.SH')
