I want to make a single dictionary from a dictionary of dictionary in python

Question

I have dictionary which contains dictionary as value for it's keys. I want to create a single dictionary out of it and also if there are keys repeating it should add the values of those keys

So I have

temp_dict = {0: {'a':1, 'b':2}, 1: {'c':3,'d':4}, 2: {'d':5,'e':6}}

I tried this for making it a single dictionary (not adding the values from same keys in this step though)

empty_dict = {}
for d in empty_dict:
    for k,v in d.items():
        empty_dict[k] = v

But the above code is also showing error. And then the next step is too add the values from same key.

I expect the output as

new_dict = {'a':1, 'b':2, 'c':3, 'd':9, 'e':6}

d has 9 by adding values from the both the 'd's above.

where is your code that you have tried and what part didn't work. People will be happy to help you. However this is not a free code writing service. — Chris Doyle, Jan 25 '19 at 16:44

You can use Counter from the stdlib

from collections import Counter

c = Counter()

for i in temp_dict.values():
    c.update(i)

Counter({'a': 1, 'b': 2, 'c': 3, 'd': 9, 'e': 6})

Thank you. This works perfectly. But is there a way to do without counter() – noob_coder Jan 25 '19 at 16:53
