解析数据解析数据
data_list = html_data['data']['list'] for i in data_list:
dit = {}
dit['股票代码'] = i['symbol'] dit['股票名字'] = i['name'] dit['当前价'] = i['current'] dit['涨跌额'] = i['chg'] dit['涨跌幅/%'] = i['percent'] dit['年初至今/%'] = i['current_year_percent'] dit['成交量'] = i['volume'] dit['成交额'] = i['amount'] dit['换手率/%'] =
