!!! note "Hinweis"
    Der Befehl `uvicorn main:app` bezieht sich auf:

    * `main`: die Datei `main.py` (das sogenannte Python-„Modul“).
    * `app`: das Objekt, welches in der Datei `main.py` mit der Zeile `app = FastAPI()` erzeugt wurde.
    * `--reload`: lässt den Server nach Codeänderungen neu starten. Verwenden Sie das nur während der Entwicklung.

각 옵션이 무엇을 의미하는지 살펴봅시다:

* 이것은 유비콘과 똑같은 문법입니다. `main`은 파이썬 모듈 네임 "`main`"을 의미하므로 `main.py`파일을 뜻합니다. 그리고 `app`은 **FastAPI** 어플리케이션이 들어 있는 변수의 이름입니다.
    * `main:app`이 파이썬의 `import` 문법과 흡사한 면이 있다는 걸 알 수 있습니다:

        ```Python
        from main import app
        ```

    * 곧, `main:app`안에 있는 콜론의 의미는 파이썬에서 `from main import app`에서의 `import`와 같습니다.

Copy that to a file `main.py`.
