如何在python中将字符串连接到每个JSON节点结果？

import json

def add_string_to_json(json_data, string):
    if isinstance(json_data, dict):
        for key, value in json_data.items():
            if isinstance(value, (dict, list)):
                add_string_to_json(value, string)
            else:
                json_data[key] = value + string
    elif isinstance(json_data, list):
        for item in json_data:
            add_string_to_json(item, string)

# 示例JSON数据
json_data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Street",
        "city": "New York"
    },
    "hobbies": ["reading", "coding"]
}

# 调用函数将字符串连接到每个JSON节点结果
add_string_to_json(json_data, " - modified")

# 打印修改后的JSON数据
print(json.dumps(json_data, indent=4))

{
    "name": "John - modified",
    "age": 30 - modified,
    "address": {
        "street": "123 Street - modified",
        "city": "New York - modified"
    },
    "hobbies": [
        "reading - modified",
        "coding - modified"
    ]
}
