如何合并两个json，并且只更新相等的dicts？

import json

def merge_json(json1, json2):
    dict1 = json.loads(json1)
    dict2 = json.loads(json2)
    
    for key, value in dict1.items():
        if key in dict2:
            if dict2[key] == value:
                continue
            else:
                dict1[key] = dict2[key]
    
    for key, value in dict2.items():
        if key not in dict1:
            dict1[key] = value
    
    merged_json = json.dumps(dict1)
    return merged_json

json1 = '{"name": "John", "age": 30, "city": "New York"}'
json2 = '{"name": "John", "age": 35, "country": "USA"}'

merged_json = merge_json(json1, json2)
print(merged_json)

{"name": "John", "age": 35, "city": "New York", "country": "USA"}
