자습시에는 모든 선택적인 의존성 및 기능을 함께 설치하는 것을 추천합니다:

<div class="termy">

```console
$ pip install "fastapi[all]"

---> 100%
```

</div>

...이는 코드를 실행하는 서버로 사용할 수 있는 `uvicorn` 또한 포함하고 있습니다.

/// note | "참고"

부분적으로 설치할 수도 있습니다.

애플리케이션을 운영 환경에 배포하려는 경우 다음과 같이 합니다:

```
pip install fastapi
```

추가로 서버 역할을 하는 `uvicorn`을 설치합니다:

```
pip install uvicorn
```

### Крок 1: імпортуємо `FastAPI`

```Python hl_lines="1"
{!../../docs_src/first_steps/tutorial001.py!}
```

`FastAPI` це клас у Python, який надає всю функціональність для API.

/// note | "Технічні деталі"

`FastAPI` це клас, який успадковується безпосередньо від `Starlette`.

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,
}
```

#### `dict`の展開

`user_dict`のような`dict`を受け取り、それを`**user_dict`を持つ関数（またはクラス）に渡すと、Pythonはそれを「展開」します。これは`user_dict`のキーと値を直接キー・バリューの引数として渡します。

そこで上述の`user_dict`の続きを以下のように書くと:

```Python
