この例では `io.BytesIO` によるメモリ内の疑似ファイルなので重要度は高くありませんが、実ファイルの場合は処理後に確実にクローズすることが重要です。

### ファイルと非同期 { #files-and-async }

多くの場合、ファイルライクオブジェクトはデフォルトでは async/await と互換性がありません。

例えば、`await file.read()` や `async for chunk in file` のような操作は提供されていません。

また、多くの場合、ディスクやネットワークから読み出すため、読み取りはブロッキング（イベントループをブロックし得る）処理になります。

/// info | 情報

上記の例は例外で、`io.BytesIO` は既にメモリ上にあるため、読み取りが何かをブロックすることはありません。
