**توجه**:

اگر با `async / await` آشنا نیستید، به بخش _"عجله‌ دارید?"_ در صفحه درباره <a href="https://fastapi.tiangolo.com/async/#in-a-hurry" target="_blank">`async` و `await` در مستندات</a> مراجعه کنید.

### اجرا کنید

با استفاده از دستور زیر سرور را اجرا کنید:

<div class="termy">

        content={"detail": jsonable_encoder(exc.errors())},
    )

* `read(size)`: Lê `size` (`int`) bytes/caracteres do arquivo.
* `seek(offset)`: Vai para o byte na posição `offset` (`int`) no arquivo.
    * Por exemplo, `await myfile.seek(0)` irá para o início do arquivo.
    * Isso é especialmente útil se você executar `await myfile.read()` uma vez e precisar ler o conteúdo novamente.
* `close()`: Fecha o arquivo.

Como todos esses métodos são métodos `assíncronos`, você precisa "aguardar" por eles.
