仅从嵌套JSON中查找已更改的属性

def find_changed_property(property_name, json_obj):
    found = False

    if isinstance(json_obj, dict):
        for key, value in json_obj.items():
            if key == property_name:

    if not found:
        print("未找到属性: ", property_name)

# 示例JSON对象
json_data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York",
        "country": "USA"
    },
    "friends": [
        {
            "name": "Alice",
            "age": 25
        },
        {
            "name": "Bob",
            "age": 35
        }
    ]
}

# 调用函数查找属性
find_changed_property("name", json_data)
