### Créer { #create-it }

Créez un fichier `main.py` avec :

```Python
from fastapi import FastAPI

app = FastAPI()


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


@app.get("/items/{item_id}")
def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}
```

現在，不再是回傳：

```json
{"message": "Hello World"}
```

...這個回應會回傳：

```json
{
  "message": "Hello World"
}
```

當然，你大概能找到比格式化 JSON 更好的方式來利用這個能力。😉
