* 這也讓我們在多種語言中可以使用自動**用戶端程式碼生成**。

### 能夠自動生成文件

FastAPI 能生成互動式 API 文件和探索性的 Web 使用者介面。由於該框架基於 OpenAPI，因此有多種選擇，預設提供了兩種。

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank"><strong>Swagger UI</strong></a> 提供互動式探索，讓你可以直接從瀏覽器呼叫並測試你的 API 。

Esto significa que **siempre tendrá un valor**, solo que a veces el valor podría ser `None` (o `null` en JSON).

Eso significa que, los clientes que usan tu API no tienen que comprobar si el valor existe o no, pueden **asumir que el campo siempre estará allí**, pero solo que en algunos casos tendrá el valor por defecto de `None`.
