How to match the keys of two dictionaries encapsulated within a list in python?

I have two dictionaries which is there within a list. The list looks like this [{'10.1.1.0':[1], '10.1.1.1':[2]}, {'10.1.1.0':[3], '10.1.1.1':[4]}]. What I need is for the same keys i.e. the matching ips I want the corresponding number or value.

Is this possible? Any help would be really appricaiated.

What you are trying to do is not possible with a dictionary in Python. Duplicate keys are not allowed. Instead you could have the same key mapped to multiple values in a list:

x = [{'10.1.1.0': [1], '10.1.1.1': [2]}, {'10.1.1.0': [3], '10.1.1.1': [4]}]
new_dict = dict() # initialize a new dictionary
for d in x: # iterate over the original list of dictionaries
    for k, v in d.items(): # get all the items in the current dictionary
        if k in new_dict: # add the key and value, or add the value to a key
            new_dict[k] += v
        else:
            new_dict[k] = v
print(new_dict)

Output:

{'10.1.1.0': [1, 3], '10.1.1.1': [2, 4]}
