Hi,

```from collections import Counter

x = {"a":200,"b":560,"y":2005,"z":2555}
y = {"a":255,"b":266,"y":3050,"z":3033}

z= Counter(x) + Counter(y)

print(z)
```

Following is the output of the program:

```>>>
>>> from collections import Counter
>>>
>>> x = {"a":200,"b":560,"y":2005,"z":2555}
>>> y = {"a":255,"b":266,"y":3050,"z":3033}
>>>
>>>
>>> z= Counter(x) + Counter(y)
>>>
>>> print(z)
Counter({'z': 5588, 'y': 5055, 'b': 826, 'a': 455})
>>>
```

In this way you can sum values.

Thanks
