Kasiyer 💁 size bir sıra numarası verir.

Beklerken askınla 😍 bir masaya oturur ve uzun bir süre konuşursunuz(Burgerleriniz çok çılgın olduğundan ve hazırlanması biraz zaman alıyor ✨🍔✨).

Hamburgeri beklerkenki zamanı 🍔, aşkının ne kadar zeki ve tatlı olduğuna hayran kalarak harcayabilirsin ✨😍✨.

Aşkınla 😍 konuşurken arada sıranın size gelip gelmediğini kontrol ediyorsun.

Você receberá uma *response* informando-o de que a data é inválida, e contendo o *body* recebido:

```JSON hl_lines="12-15"

`UploadFile` has the following `async` methods. They all call the corresponding file methods underneath (using the internal `SpooledTemporaryFile`).

* `write(data)`: Writes `data` (`str` or `bytes`) to the file.
* `read(size)`: Reads `size` (`int`) bytes/characters of the file.
* `seek(offset)`: Goes to the byte position `offset` (`int`) in the file.
    * E.g., `await myfile.seek(0)` would go to the start of the file.

## Sub-dependencies with `yield`

You can have sub-dependencies and "trees" of sub-dependencies of any size and shape, and any or all of them can use `yield`.

**FastAPI** will make sure that the "exit code" in each dependency with `yield` is run in the correct order.
