/// tip

The syntax `{"name", "description"}` creates a `set` with those two values.

It is equivalent to `set(["name", "description"])`.

///

#### Using `list`s instead of `set`s { #using-lists-instead-of-sets }

If you forget to use a `set` and use a `list` or `tuple` instead, FastAPI will still convert it to a `set` and it will work correctly:

	}

	return sys.store.ListPolicies(ctx, bucketName)
}

## リストのフィールド { #list-fields }

属性をサブタイプとして定義することができます。例えば、Pythonの`list`:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

これにより、各項目の型は宣言されていませんが、`tags`はリストになります。

## タイプパラメータを持つリストのフィールド { #list-fields-with-type-parameter }

しかし、Pythonには内部の型、または「タイプパラメータ」を使ってリストを宣言するための特定の方法があります:

### タイプパラメータを持つ`list`の宣言 { #declare-a-list-with-a-type-parameter }

	NextPartNumberMarker int
	MaxParts             int
	IsTruncated          bool

	ChecksumAlgorithm string
	ChecksumType      string

	// List of parts.
	Parts []Part `xml:"Part"`
}

// ListMultipartUploadsResponse - format for list multipart uploads response.
type ListMultipartUploadsResponse struct {
	XMLName xml.Name `xml:"http://s3.amazonaws.com/doc/2006-03-01/ ListMultipartUploadsResult" json:"-"`

## List of models { #list-of-models }

The same way, you can declare responses of lists of objects.

For that, use the standard Python `list`:

{* ../../docs_src/extra_models/tutorial004_py310.py hl[18] *}

## Response with arbitrary `dict` { #response-with-arbitrary-dict }
