熊猫多列比较

我有一个带有数据框的列的列表：

Df = ["correct_New", "miss_New", "wrong_New", "correct_Old","miss_Old","wrong_Old"]
ListNew = ["correct_New", "miss_New", "wrong_New"]
ListOld = ["correct_Old","miss_Old","wrong_Old"]

#Dropping equivalent
df_merge_files  = Df[ListNew] != Df[ListOld]

#Going to save only the differences. 
df_merge_files.to_csv("comparison_report.csv", sep=';', index=False)
ValueError：只能比较标记相同的DataFrame对象
