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

此處，`new_dict` 會包含 `old_dict` 的所有鍵值配對，再加上新的鍵值配對：

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

你可以用這個技巧在「路徑操作」中重用一些預先定義的回應，並與其他自訂回應結合。
