重要なのは、**`Annotated` の中で関数と一緒に `AfterValidator` を使うこと** だけです。この部分は飛ばしても構いません。 🤸

ただし、この具体的なコード例が気になっていて、まだ興味が続くなら、追加の詳細を示します。

#### `value.startswith()` を使う文字列 { #string-with-value-startswith }

気づきましたか？`value.startswith()` を使う文字列はタプルを受け取れ、そのタプル内の各値をチェックします:

{* ../../docs_src/query_params_str_validations/tutorial015_an_py310.py ln[16:19] hl[17] *}

#### ランダムなアイテム { #a-random-item }

1.  `envs/*` are lists of variables made with bash syntax. A user must set a
    `TFCI` env param pointing to a list of `env` files.
2.  `utilities/setup.sh`, initialized by all top-level scripts, reads and sets
    values from those `TFCI` paths.
    -   `set -a` / `set -o allexport` exports the variables from `env` files so
        all scripts can use them.
    -   `utilities/setup_docker.sh` creates a container called `tf` with all

// initialized to its zero value.
// Otherwise, the argument is an expression x and new(x) allocates a variable
