如何在json中添加递归函数的结果？

import json

def recursive_function(json_obj):
    for key, value in json_obj.items():
        if isinstance(value, dict):
            # 递归处理嵌套的 JSON 对象
            json_obj[key] = recursive_function(value)
        elif isinstance(value, str):
            # 处理字符串类型的值，例如添加前缀
            json_obj[key] = "processed_" + value
    return json_obj

# 假设原始的 JSON 对象如下
original_json = {
    "key1": "value1",
    "key2": {
        "nested_key1": "nested_value1",
        "nested_key2": {
            "deep_key": "deep_value"
        }
    }
}

# 调用递归函数进行处理
processed_json = recursive_function(original_json)

# 输出处理后的 JSON
print(json.dumps(processed_json, indent=4))
