如果你为使用了标签的 FastAPI 应用生成客户端，通常也会根据标签来拆分客户端代码。

这样你就可以在客户端代码中把内容正确地组织和分组：

<img src="/img/tutorial/generate-clients/image06.png">

在这个例子中，你会有：

* `ItemsService`
* `UsersService`

### 客户端方法名 { #client-method-names }

现在，像 `createItemItemsPost` 这样的生成方法名看起来不太简洁：

```TypeScript
ItemsService.createItemItemsPost({name: "Plumbus", price: 5})
```

...这是因为客户端生成器会把每个*路径操作*的 OpenAPI 内部**操作 ID（operation ID）**用作方法名的一部分。

Nous pouvons alors remplacer la dépendance « dependable » `common_parameters` ci‑dessus par la classe `CommonQueryParams` :

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[11:15] *}

Faites attention à la méthode `__init__` utilisée pour créer l'instance de la classe :

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

... il a les mêmes paramètres que notre précédent `common_parameters` :

        byte[] data = new byte[] { 0x78, 0x56, 0x34, 0x12 };
        PacDataInputStream pdis = createInputStream(data);
        SID sid = pdis.readId();
        // The readId method creates a SID with authority 5 and the RID value
        // Expected format: S-1-5-305419896
        String sidString = sid.toString();
        assertNotNull(sidString);
        assertEquals("S-1-5-305419896", sidString);

Then, we can change the dependency "dependable" `common_parameters` from above to the class `CommonQueryParams`:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[11:15] *}

Pay attention to the `__init__` method used to create the instance of the class:

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[12] *}

...it has the same parameters as our previous `common_parameters`:

     * Verifies that the new implementation correctly reads entire resource content.

## Read env vars in Python { #read-env-vars-in-python }

You could also create environment variables **outside** of Python, in the terminal (or with any other method), and then **read them in Python**.

For example you could have a file `main.py` with:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

    @SuppressWarnings("Interruption")
    public void run() {
      // If either of these reads return null then we must be after a successful cancel or another
      // call to this method.
      TimeoutFuture<V> timeoutFuture = timeoutFutureRef;
      if (timeoutFuture == null) {
        return;
      }
      @RetainedLocalRef ListenableFuture<V> delegate = timeoutFuture.delegateRef;
