Python sum dictionary values by key

Hi,

In python we can easily create dictionary and store the values in it. In dictionary we store the values in key value pair.

I have two dictionary with same keys and different numeric values. We are getting these two dictionaries from two different web services.

We want to merge these dictionaries into one and sum the dictionary values by key.

What is the code for Python sum dictionary values by key?

Thanks

Hi,

Here is complete example code for summing dictionary values:

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)

Thanks
