Certifique-se de criar um [ambiente virtual](../../virtual-environments.md), ativá-lo e então instalar o `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | Informação

Se você pretente utilizar algoritmos de assinatura digital como o RSA ou o ECDSA, você deve instalar a dependência da biblioteca de criptografia `pyjwt[crypto]`.

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```


/// info | 信息

`**second_user_data` 意思是：

直接将 `second_user_data` 字典的键和值作为 key-value 参数传入，等同于：`User(id=4, name="Mary", joined="2018-11-30")`
