## Voorbeeld

### Creëer het

* Maak het bestand `main.py` aan met daarin:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

### 타입 매개변수를 활용한 Generic(제네릭) 타입

`dict`, `list`, `set`, `tuple`과 같은 값을 저장할 수 있는 데이터 구조가 있고, 내부의 값은 각자의 타입을 가질 수도 있습니다.

타입과 내부 타입을 선언하기 위해서는 파이썬 표준 모듈인 `typing`을 이용해야 합니다.

구체적으로는 아래 타입 힌트를 지원합니다.

#### `List`

예를 들면, `str`의 `list`인 변수를 정의해봅시다.

`typing`에서  `List`(대문자 `L`)를 import 합니다.

```Python hl_lines="1"
{!../../docs_src/python_types/tutorial006.py!}
```

콜론(`:`) 문법을 이용하여 변수를 선언합니다.

## Exemple

### Créez

* Créez un fichier `main.py` avec :

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

<div class="termy">

```console
$ pip install "uvicorn[standard]"

---> 100%
```

</div>

## 範例

### 建立

- 建立一個 python 檔案 `main.py`，並寫入以下程式碼：

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
