如何检查和分类json数组中的key是否具有相同的值？

import json

def check_and_classify_keys(json_array):
    values_dict = {}
    different_value_keys = []
    same_value_keys = []

    for obj in json_array:
        for key, value in obj.items():
            if key not in values_dict:
                values_dict[key] = value
            elif values_dict[key] != value:
                values_dict[key] = "不同值"
                different_value_keys.append(key)

    for key, value in values_dict.items():
        if value == "不同值":
            different_value_keys.append(key)
        else:
            same_value_keys.append(key)

    return {
        "具有不同值的key": different_value_keys,
        "具有相同值的key": same_value_keys
    }

# 示例用法
json_str = '[{"key1": "value1", "key2": "value2"}, {"key1": "value1", "key2": "value3"}]'
json_array = json.loads(json_str)

result = check_and_classify_keys(json_array)
print("具有不同值的key:", result["具有不同值的key"])
print("具有相同值的key:", result["具有相同值的key"])
