## Jalankan kode

Semua blok-blok kode dapat disalin dan digunakan langsung (Mereka semua sebenarnya adalah file python yang sudah teruji).

Untuk menjalankan setiap contoh, salin kode ke file `main.py`, dan jalankan `uvicorn` dengan:

<div class="termy">

```console
$ uvicorn main:app --reload

<img src="/img/tutorial/separate-openapi-schemas/image02.png">
</div>

Isso significa que ele **sempre terá um valor**, só que às vezes o valor pode ser `None` (ou `null` em termos de JSON).

Isso quer dizer que, os clientes que usam sua API não precisam verificar se o valor existe ou não, eles podem **assumir que o campo sempre estará lá**, mas que em alguns casos terá o valor padrão de `None`.

elif _tf_api_dir not in __path__:
  __path__.append(_tf_api_dir)
