遍历嵌套对象并修改特定属性的解决方法可以使用递归函数来实现。以下是一个示例代码：

def update_nested_object(obj, target_property, new_value):
    if isinstance(obj, dict):
        for key, value in obj.items():
            if key == target_property:
                obj[key] = new_value
            elif isinstance(value, (dict, list)):
                update_nested_object(value, target_property, new_value)
    elif isinstance(obj, list):
        for item in obj:
            if isinstance(item, (dict, list)):
                update_nested_object(item, target_property, new_value)

# 示例数据
data = {
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Main St",
        "city": "New York",
        "state": "NY"
    },
    "friends": [
        {
            "name": "Alice",
            "age": 25
        },
        {
            "name": "Bob",
            "age": 35
        }
    ]
}

# 将所有名为"age"的属性值修改为40
update_nested_object(data, "age", 40)

print(data)

运行以上代码会将示例数据中所有名为"age"的属性值修改为40。
