def down_data():
rsa = bs.query_all_stock(day="2021-12-17")
data_df = []
rsa = bs.query_history_k_data_plus("sz.300251",
"date,code,open,high,low,close,volume,amount",

while (rsa.error_code == '0') & rsa.next():
data_df.append(rsa.get_data())
result = pd.DataFrame(data_df, columns=rsa.fields)
print(result)
打印错误 ：ValueError: Must pass 2-d input. shape=(1, 8, 8)
直接打印data_df格式是[1,2,3,4,5,6,[8 rows x 8 columns] ] 一样不能处理
直接将获取的数据写成数据框即可，不要再添加进列表。代码如下：
def down_data():
rsa = bs.query_all_stock(day="2021-12-17")
rsa = bs.query_history_k_data_plus("sz.300251",
"date,code,open,high,low,close,volume,amount",
start_date="2021-12-17", end_date="2021-12-28", frequency="d", adjustflag="3")
while (rsa.error_code == '0') & rsa.next():
result = pd.DataFrame(rsa.get_data(), columns=rsa.fields)
print(result)
运行结果：

应该是数据格式不对，先确认pd.DataFrame的第一个参数是不是列表格式
