情况

处理一些数据，需要新建一个dataframe，后续再新增数据进去，使用代码如下：

    df=pd.DataFrame(columns=[\'code\', \'name\'])
    for row in results:
        i= i+1
        print(i)
        print("总数%s, 当前%s 编码%s" % (str(cursor.rowcount), str(i), row[0]))
        codeValue = row[0]
        nameValue = row[1]
		temp=[{\'code\':codeValue,\'name\':nameValue}]
		df=df.append(temp)

报错AttributeError: type object ‘object’ has no attribute \'dtype’如下：
