The parameter that defines this is `default_response_class`.

In the example below, **FastAPI** will use `HTMLResponse` by default, in all *path operations*, instead of JSON.

{* ../../docs_src/custom_response/tutorial010_py310.py hl[2,4] *}

/// tip

You can still override `response_class` in *path operations* as before.

## 事前定義レスポンスとカスタムの組み合わせ { #combine-predefined-responses-and-custom-ones }

多くの *path operations* に適用できる事前定義のレスポンスを用意しつつ、各 *path operation* ごとに必要なカスタムレスポンスと組み合わせたい場合があります。

そのような場合、Python の `**dict_to_unpack` による `dict` の「アンパック」テクニックを使えます:

```Python
old_dict = {
    "old key": "old value",
