Combining two dictionaries into one with the same keys?

Question

I\'ve looked through a few of the questions here and none of them seem to be exactly my problem. Say I have 2 dictionaries, and they are dict1

{\'A\': 25 ,          


        

Answer 1

Use pydash

from pydash import merge_with
cbk = lambda obj_val, src_val: obj_val + src_val
obj1 = {'a': [1], 'b': [2]}
obj2 = {'a': [3], 'b': [4]}
res = merge_with(obj1, obj2, cbk)
print(res)

Result:

{'a': [1, 3], 'b': [2, 4]}

you can also use dictlib

import dictlib
obj1 = {'a': [1], 'b': [2]}
obj2 = {'a': [3], 'b': [4],"c":[3]}
c = dictlib.union_setadd(obj1, obj2)
print(c)    
{'a': [1, 3], 'b': [2, 4], 'c': [3]}
