/// tip

The second argument to [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) is the default value to return.

If not provided, it's `None` by default, here we provide `"World"` as the default value to use.

///

Then you could call that Python program:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console

```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}
```

Now in the same project directory create a file `Dockerfile` with:

```{ .dockerfile .annotate }

`Query`에 동일한 매개변수를 선언할 수 있습니다.

예를 들어, 경로 매개변수 `item_id`에 `title` 메타데이터 값을 선언하려면 다음과 같이 입력할 수 있습니다:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note | 참고

경로 매개변수는 경로의 일부여야 하므로 언제나 필수입니다. `None`으로 선언하거나 기본값을 지정하더라도 아무 영향이 없으며, 항상 필수입니다.

`Annotated`를 사용한다면 이것은 아마 그렇게 중요하지 않거나 필요하지 않을 수 있습니다.
