How do you combine two dictionary values for common keys

Hi,

I have two dictionary and I want to combine the values based on the key in new dictionary.

For example if we have following two dictionary:

d1 = {"a":200, "b":200, "c":500}

d2 = {"a":300, "b":300, "c":800}

The final dictionary should be::

final = {"a":500, "b":500, "c":1300}

Hi,

Here is the final program that sums values from two dictionary:

from collections import Counter

d1 = {"a":200, "b":200, "c":500}

d2 = {"a":300, "b":300, "c":800}

combinedDict = Counter(d1) + Counter(d2)
print(combinedDict)

Above example program shows you how to combine two dictionary values for common keys.

If you run the program you will get following output:

>>> 
>>> from collections import Counter
>>> 
>>> d1 = {"a":200, "b":200, "c":500}
>>> 
>>> d2 = {"a":300, "b":300, "c":800}
>>> 
>>> combinedDict = Counter(d1) + Counter(d2)
>>> print(combinedDict)
Counter({'c': 1300, 'a': 500, 'b': 500})
>>>

Thanks
