Percebeu? Uma string usando `value.startswith()` pode receber uma tupla, e verificará cada valor na tupla:

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

#### Um item aleatório { #a-random-item }

Com `data.items()` obtemos um <dfn title="Algo que podemos iterar com um laço for, como uma list, set, etc.">objeto iterável</dfn> com tuplas contendo a chave e o valor de cada item do dicionário.

 *
 * This nesting is typical but not strict. For example, when calls use "Expect: continue" the
 * request body start and end events occur within the response header events. Similarly,
 * [duplex calls][RequestBody.isDuplex] interleave the request and response bodies.
 *
 * Since connections may be reused, the proxy selection, DNS, and connect events may not be present

// - a string representing the tracing implementation: "mlir" or "graphdef".
// - a boolean that when true enables TFRT as the execution engine.

        and `audio_dataset_from_directory`, to be used with the
        `validation_split` argument, for returning both dataset splits at once,
        as a tuple.
    *   Added `tf.keras.utils.split_dataset` utility to split a `Dataset` object
        or a list/tuple of arrays into two `Dataset` objects (e.g. train/test).
    *   Added step granularity to `BackupAndRestore` callback for handling

`{"name", "description"}` の構文は、それら2つの値を持つ `set` を作成します。

これは `set(["name", "description"])` と同等です。

///

#### `set`の代わりに`list`を使用する { #using-lists-instead-of-sets }

もし `set` を使用することを忘れて、代わりに `list` や `tuple` を使用しても、FastAPIはそれを `set` に変換して正しく動作します:
