How to merge dictionaries of dictionaries?

Question

I need to merge multiple dictionaries, here\'s what I have for instance:

dict1 = {1:{\"a\":{A}}, 2:{\"b\":{B}}}

dict2 = {2:{\"c\":{C}}, 3:{\"d\":{D}}
         


        

Answer 1

This should help in merging all items from dict2 into dict1:

for item in dict2:
    if item in dict1:
        for leaf in dict2[item]:
            dict1[item][leaf] = dict2[item][leaf]
    else:
        dict1[item] = dict2[item]

Please test it and tell us whether this is what you wanted.

EDIT:

The above mentioned solution merges only one level, but correctly solves the example given by OP. To merge multiple levels, the recursion should be used.
