map[desc:RGB colors:[red green blue]]
map[desc:CMYK colors:[cyan magenta yellow black]]
```

likewise, increasing depth level to `3` yields:
```
red
green
blue
cyan
magenta
yellow
black
```

optionally, kev:value pairs can be emitted as an individual struct:
```go
decoder := jstream.NewDecoder(f, 2).EmitKV() // enable KV streaming at a depth level of 2
```

```
jstream.KV{desc RGB}

          ?: throw ProtocolException(
            "Unexpected status line: $statusLine",
          )

      // Parse an optional response message like "OK" or "Not Modified". If it
      // exists, it is separated from the response code by a space.
      var message = ""
      if (statusLine.length > codeStart + 3) {

* 変数`prices`は`dict`であり:
    * この`dict`のキーは`str`型です。（つまり、各項目の名前）
    * この`dict`の値は`float`型です。（つまり、各項目の価格）

#### `Optional`

また、`Optional`を使用して、変数が`str`のような型を持つことを宣言することもできますが、それは「オプション」であり、`None`にすることもできます。

```Python hl_lines="1 4"
{!../../docs_src/python_types/tutorial009.py!}
```

ただの`str`の代わりに`Optional[str]`を使用することで、エディタは値が常に`str`であると仮定している場合に実際には`None`である可能性があるエラーを検出するのに役立ちます。

#### ジェネリック型
