对于这些情况，你可以使用Python的技术，将 `dict` 与 `**dict_to_unpack` 解包：
```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

这里， new_dict 将包含来自 old_dict 的所有键值对加上新的键值对：
```python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```
您可以使用该技术在路径操作中重用一些预定义的响应，并将它们与其他自定义响应相结合。
**例如：**

  // +optional
  optional string restartPolicy = 3;

  // Optional duration in seconds the carp needs to terminate gracefully. May be decreased in delete request.
  // Value must be non-negative integer. The value zero indicates delete immediately.
  // If this value is nil, the default grace period will be used instead.
  // The grace period is the duration in seconds after the processes running in the carp are sent
