在這些情況下，你可以使用 Python 的「解包」`dict` 技巧，透過 `**dict_to_unpack`：

```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",
}
```

    public void addNewIPAddress(InetAddress address) {
        newIPAddresses.add(new WitnessIPAddress(address));
    }

    /**
     * Adds an old IP address to the notification.
     *
     * @param address the old IP address
     */
    public void addOldIPAddress(InetAddress address) {
        oldIPAddresses.add(new WitnessIPAddress(address));
    }

    // Getters and Setters

   * Creates a {@code ObjectCountLinkedHashMap} instance, with a high enough "initial capacity" that
   * it <i>should</i> hold {@code expectedSize} elements without growth.
   *
   * @param expectedSize the number of elements you expect to add to the returned set
   * @return a new, empty {@code ObjectCountLinkedHashMap} with enough capacity to hold {@code
   *     expectedSize} elements without resizing

This means that you can install the latest version of Pydantic v2 and import and use the old Pydantic v1 components from this submodule, as if you had the old Pydantic v1 installed.

```Python
old_dict = {

    "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",
}
