如何查找和计算JSON中的所有对象

import json

def find_and_calculate_objects(json_data):
    count = 0
    total_value = 0

    def traverse(obj):
        nonlocal count, total_value

        if isinstance(obj, dict):
            for key, value in obj.items():
                if isinstance(value, dict) or isinstance(value, list):
                    traverse(value)
                else:
                    # 对象计数和值累加
                    count += 1
                    total_value += value
        elif isinstance(obj, list):
            for item in obj:
                traverse(item)

    # 解析JSON
    data = json.loads(json_data)

    # 遍历JSON并计算对象
    traverse(data)

    return count, total_value

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

# 调用函数查找和计算对象
obj_count, obj_value = find_and_calculate_objects(json_data)

print("对象数量:", obj_count)
print("对象值之和:", obj_value)

对象数量: 6
对象值之和: 93
