如何获得Python中两个字典之间的差异？ - How to get the difference between two dictionaries in Python?

问题：

I have two dictionaries, and I need to find the difference between the two, which should give me both a key and a value.我有两本字典，我需要找出两者之间的区别，这应该给我一个键和一个值。

I have searched and found some addons/packages like datadiff and dictdiff-master, but when I try to import them in Python 2.7, it says that no such modules are defined.我搜索并找到了一些插件/包，如 datadiff 和 dictdiff-master，但是当我尝试在 Python 2.7 中导入它们时，它说没有定义这样的模块。

I used a set here:我在这里使用了一套：

first_dict = {}
second_dict = {}
 
value = set(second_dict) - set(first_dict)
print value

My output is:我的输出是：

>>> set(['SCD-3547', 'SCD-3456'])

I am getting only keys, and I need to also get the values.我只得到键，我还需要得到值。
