Здесь переменная `app` будет экземпляром класса `FastAPI`.

Это будет основная точка взаимодействия для создания всего вашего API.

### Шаг 3: создайте *операцию пути (path operation)* { #step-3-create-a-path-operation }

#### Путь (path) { #path }

Здесь «путь» — это последняя часть URL, начиная с первого символа `/`.

Итак, в таком URL:

```
https://example.com/items/foo
```

...путь будет:

        @app.get("/path_example/{item_id}")
        def path_example(
            item_id: str = Path(
                example="item_1",

        ):
            return item_id

    @app.get("/path_examples/{item_id}")
    def path_examples(
        item_id: str = Path(
            examples=["item_1", "item_2"],
        ),
    ):
        return item_id

	}
