from typing import Optional


def say_hi(name: Optional[str]):
    print(f"Hey {name}!")
```

Параметр `name` объявлен как `Optional[str]`, но он не является необязательным: вы не можете вызвать функцию без этого параметра:

```Python
say_hi()  # О нет, это вызывает ошибку! 😱
```

Параметр `name` по-прежнему обязателен (не «optional»), так как у него нет значения по умолчанию. При этом `name` принимает `None` в качестве значения:

                "schemas": {
                    "Item": {
                        "title": "Item",
                        "required": ["name", "price"],
                        "type": "object",
                        "properties": {
                            "name": {"title": "Name", "type": "string"},
                            "price": {"title": "Price", "type": "number"},
                            "description": {
