Assuming,

```
dict1 = { "A" : ["a","b","c"]} # old one
dict2 = { "A" : ["a","b","c","d"]} # new one
#i wanna get
dict3 = {"A":["d"]}
```

as i know, taking up ‘deepdiif’ isn’t right because it has to have same architecture of Dictionary

how can i get that diffrence of added datas of Dictionary in simple and easy way?

### >Solution :

You can do this with `set.symmetric_difference()`

:

```
set(*dict1.values()).symmetric_difference(*dict2.values())
```

If you have more dictionary keys than just one:

```
In [2]: dict1
Out[2]: {'A': ['a', 'b', 'c'], 'B': [1, 2, 3, 4]}
In [3]: dict2
Out[3]: {'A': ['a', 'b', 'c', 'd'], 'B': [4, 3, 2]}
In [4]: {k: list(set(dict1[k]).symmetric_difference(dict2[k])) for k in dict1}
Out[4]: {'A': ['d'], 'B': [1]}
```
