这段响应项解析代码会输出什么？

response = {
    "status": "completed",
    "output": [
        {"type": "reasoning", "summary": []},
        {"type": "message", "content": [
            {"type": "output_text", "text": "billing"},
        ]},
    ],
}
texts = [
    block["text"]
    for item in response["output"] if item["type"] == "message"
    for block in item["content"] if block["type"] == "output_text"
]
print(response["status"], "".join(texts))
