```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

여기서 `new_dict`는 `old_dict`의 모든 키-값 쌍에 더해 새 키-값 쌍까지 포함합니다:

```Python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```

```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，再加上新的键值对：

```Python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```

你可以使用该技巧在*路径操作*中重用一些预定义响应，并把它们与额外的自定义响应组合在一起。
