从python中的嵌套json数组中提取数据

def extract_data_from_json(json_array, keyword):
    for item in json_array:
        if isinstance(item, dict):
            result = extract_data_from_json(item.values(), keyword)
            if result is not None:
                return result
        elif isinstance(item, list):
            result = extract_data_from_json(item, keyword)
            if result is not None:
                return result
        elif item == keyword:
            return item

# 示例用法
json_data = {
    "name": "John",
    "age": 30,
    "nested_array": [
        {
            "id": 1,
            "value": "Hello"
        },
        {
            "id": 2,
            "value": "World"
        }
    ]
}

result = extract_data_from_json(json_data.values(), "Hello")
print(result)  # 输出：Hello

def extract_data_from_json(json_array, keyword):

        item = queue.pop(0)
        if isinstance(item, dict):
            queue.extend(item.values())
        elif isinstance(item, list):
