つまり:

* `100`以上は「情報」のためのものです。。直接使うことはほとんどありません。これらのステータスコードを持つレスポンスはボディを持つことができません。
* **`200`** 以上は「成功」のレスポンスのためのものです。これらは最も利用するであろうものです。
    * `200`はデフォルトのステータスコードで、すべてが「OK」であったことを意味します。
    * 別の例としては、`201`（Created）があります。これはデータベースに新しいレコードを作成した後によく使用されます。
    * 特殊なケースとして、`204`（No Content）があります。このレスポンスはクライアントに返すコンテンツがない場合に使用されます。そしてこのレスポンスはボディを持つことはできません。

Underneath, the `open("./somefile.txt")` creates an object that is called a "Context Manager".

When the `with` block finishes, it makes sure to close the file, even if there were exceptions.

When you create a dependency with `yield`, **FastAPI** will internally create a context manager for it, and combine it with some other related tools.

 * Immutable empty instances are returned for collection types; {@code ""} for string; {@code 0} for
 * number types; reasonable default instance for other stateless types. For mutable types, a fresh
 * instance is created each time {@code get()} is called.
