    * `dict`의 값(value)는 `float`타입이다. (각 아이템의 가격(price))

#### `Optional`

`str`과 같이 타입을 선언할 때 `Optional`을 쓸 수도 있는데, "선택적(Optional)"이기때문에 `None`도 될 수 있습니다:

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial009.py!}
```

`Optional[str]`을 `str` 대신 쓰게 되면, 특정 값이 실제로는 `None`이 될 수도 있는데 항상 `str`이라고 가정하는 상황에서 에디터가 에러를 찾게 도와줄 수 있습니다.

#### Generic(제네릭) 타입

## Псевдонимы параметров

Представьте, что вы хотите использовать query-параметр с названием `item-query`.

Например:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

    // Expire the two present elements.
    fakeTicker.advance(1001, MILLISECONDS);

    cache.getIfPresent(23);
    cache.getIfPresent(56);

    // Add two elements and invalidate them.
    cache.put(1, 4);
    cache.put(2, 8);

    cache.invalidateAll();

    assertEquals(2, stats[0]);
    assertEquals(2, stats[1]);
    assertEquals(4, stats[2]);
    assertEquals(3, stats[3]);
  }
