sign = md5("{token}-{id}-{publish_time}-{nonce}-{server_time}")Python/Go/Java/PHP 示例代码如下：

上述代码都是用 LLM 生成的，使用的 prompts 如下:
md
我有一个签名的计算方式为：
sign = md5("{token}-{id}-{publish_time}-{nonce}-{server_time}")
其中：
- token: str, eg "your_token"
- id: str, eg "your_id"
- publish_time: int64, eg 1234567890
- nonce: str, eg "your_nonce"
- server_time: int64, eg 9876543210
帮我编写对应的 Python&Go 的 demo，并用样例数据验证签名计算是否为 `ed72493981fff6ddc4770dc70aeeb1ad`。请根据自己的需求修改 prompts，并用样例数据验证签名计算是否正确。
