结果出现错误，为什么呢？
结果如下
[Getting data:]#[Getting data:]#Traceback (most recent call last):
  File "C:/Users/fm-hbs/Desktop/test.py", line 16, in <module>
    df = pd.concat([df_qjd.close,df_gm.close], axis =1, keys=['df_qjd.close', 'df_gm.close'])#合并

错误在这一行，df = pd.concat([df_qjd.close,df_gm.close], axis =1, keys=['df_qjd.close', 'df_gm.close'])#合并，根据他的提示应该是close这个属性没有匹配上

怎么修改呢？

Seawolf

一是检查一下两个dataFrame里的close ，二是查一下df_qjd.close,df_gm.close这两个参数属不属于dataFrame类型
