`FastAPI`는 당신의 API를 위한 모든 기능을 제공하는 파이썬 클래스입니다.

/// note | 기술 세부사항

`FastAPI`는 `Starlette`를 직접 상속하는 클래스입니다.

`FastAPI`로 <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a>의 모든 기능을 사용할 수 있습니다.

///

### 2 단계: `FastAPI` "인스턴스" 생성

{* ../../docs_src/first_steps/tutorial001.py hl[3] *}

{* ../../docs_src/first_steps/tutorial001.py h1[1] *}

`FastAPI` 是一個 Python 類別，提供所有 API 的全部功能。

/// note | Technical Details

`FastAPI` 是一個直接繼承自 `Starlette` 的類別。

你同樣可以透過 `FastAPI` 來使用 <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> 所有的功能。

///

### 第二步：建立一個 `FastAPI` 「實例」

{* ../../docs_src/first_steps/tutorial001.py h1[3] *}

這裡的 `app` 變數將會是 `FastAPI` 類別的「實例」。
