Sonrasında veriyi dönüştürür ve doğrular. Böylece `settings` nesnesini kullandığınızda, tanımladığınız tiplerde verilere sahip olursunuz (örn. `items_per_user` bir `int` olur).

### `settings`'i kullanın { #use-the-settings }

Daha sonra uygulamanızda yeni `settings` nesnesini kullanabilirsiniz:

{* ../../docs_src/settings/tutorial001_py310.py hl[18:20] *}

	Password           string   `json:"password"`
	Database           string   `json:"database"`
	QueueDir           string   `json:"queueDir"`
	QueueLimit         uint64   `json:"queueLimit"`
	MaxOpenConnections int      `json:"maxOpenConnections"`
}

// Validate MySQLArgs fields
func (m MySQLArgs) Validate() error {
	if !m.Enable {
		return nil
	}

	if m.Format != "" {
		f := strings.ToLower(m.Format)

```Python hl_lines="1"
async def get_burgers(number: int):
    # Виконайте деякі асинхронні дії, щоб створити бургери
    return burgers
```

...замість `def`:

```Python hl_lines="2"
# Це не асинхронно
def get_sequential_burgers(number: int):
    # Виконайте деякі послідовні дії, щоб створити бургери
    return burgers
```

```

そして呼び出すと:

```Python
user_dict = user_in.model_dump()
```

これで変数`user_dict`のデータを持つ`dict`ができました。（これはPydanticモデルのオブジェクトの代わりに`dict`です）。

そして呼び出すと:

```Python
print(user_dict)
```

以下のようなPythonの`dict`を得ることができます:

```Python
{
    'username': 'john',
    'password': 'secret',
    'email': '******@****.***',
    'full_name': None,
}
```

Например, [можно использовать `with` для чтения файла](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Под капотом вызов `open("./somefile.txt")` создаёт объект, называемый «контекстным менеджером».

Когда блок `with` завершается, он обязательно закрывает файл, даже если были исключения.

    void tryAcquireSuccessfully(long timeoutMillis) {
      assertTrue(tryAcquireUninterruptibly(semaphore, timeoutMillis, MILLISECONDS));
      completed.assertCompletionExpected();
    }

    void tryAcquireSuccessfully(int permits, long timeoutMillis) {
      assertTrue(tryAcquireUninterruptibly(semaphore, permits, timeoutMillis, MILLISECONDS));
      completed.assertCompletionExpected();
    }

    /**

These requirements apply to the modified work as a whole. If

For example, [you can use `with` to read a file](https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files):

```Python
with open("./somefile.txt") as f:
    contents = f.read()
    print(contents)
```

Underneath, the `open("./somefile.txt")` creates an object that is called a "Context Manager".

When the `with` block finishes, it makes sure to close the file, even if there were exceptions.
