## Importez le `BaseModel` de Pydantic

Commencez par importer la classe `BaseModel` du module `pydantic` :

{* ../../docs_src/body/tutorial001.py hl[4] *}

## Créez votre modèle de données

Déclarez ensuite votre modèle de données en tant que classe qui hérite de `BaseModel`.

Utilisez les types Python standard pour tous les attributs :

     <span style="background-color:#007166"><font color="#D3D7CF"> code </font></span>  Importing the FastAPI app object from the module with
             the following code:

/// tip | Подсказка

Иногда при попытке обновить pip вы можете получить ошибку **`No module named pip`**.

Если это произошло, установите и обновите pip с помощью команды ниже:

<div class="termy">

```console
$ python -m ensurepip --upgrade

---> 100%
```

</div>

         * So this is probably just the "Windows Java 8" case. In that case, if we wanted *another*
         * layer of fallback before consulting the system property, we could try
         * com.sun.security.auth.module.NTSystem.
         *
         * But for now, we use the value from the system property as our best guess.

        return fromSystemProperty;

You could load it at the top level of the module/file, but that would also mean that it would **load the model** even if you are just running a simple automated test, then that test would be **slow** because it would have to wait for the model to load before being able to run an independent part of the code.

 *  New: `Authenticator.JAVA_NET_AUTHENTICATOR` forwards authentication requests to
    `java.net.Authenticator`. This obsoletes `JavaNetAuthenticator` in the `okhttp-urlconnection`
    module.

 *  New: `CertificatePinner` now offers an API for inspecting the configured pins.

 *  Upgrade: [Okio 2.6.0][okio_2_6_0].
