```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。

例如：

        @Override
        public java.util.Enumeration<String> getInitParameterNames() {
            return null;
        }

        @Override
        public boolean setInitParameter(String name, String value) {
            return false;
        }

        @Override
        public void setAttribute(String name, Object object) {
        }

        @Override
        public void removeAttribute(String name) {

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

Aquí, `new_dict` contendrá todos los pares clave-valor de `old_dict` más el nuevo par clave-valor:

```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"}
```

Hier wird `new_dict` alle Schlüssel-Wert-Paare von `old_dict` plus das neue Schlüssel-Wert-Paar enthalten:

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

                    "Item": {
                        "title": "Item",
                        "required": ["id", "value"],
                        "type": "object",
                        "properties": {
                            "id": {"title": "Id", "type": "string"},
                            "value": {"title": "Value", "type": "string"},
                        },
                    },
                    "Message": {

						if value := reflect.ValueOf(values[idx]).Elem(); value.Kind() == reflect.Ptr && value.IsNil() {
							isNilPtrValue = true
							break
						}

						relValue.Set(reflect.New(relValue.Type().Elem()))
						joinedNestedSchemaMap[fullRelsName] = nil
					}
				}
				currentReflectValue = relValue
			}

			if !isNilPtrValue { // ignore if value is nil

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

Ici, `new_dict` contiendra toutes les paires clé-valeur de `old_dict` plus la nouvelle paire clé-valeur :

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