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}
How to combine values in a new dictionary?
I want example code in Python. How do you combine two dictionary values for common keys?
Share me running code.
Thanks

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
