* `seek(versatz)`: Geht zur Position `versatz` (`int`) in der Datei.
    * Z. B. würde `await myfile.seek(0)` zum Anfang der Datei gehen.
    * Das ist besonders dann nützlich, wenn Sie `await myfile.read()` einmal ausführen und dann diese Inhalte erneut auslesen müssen.
* `close()`: Schließt die Datei.

Da alle diese Methoden `async`hron sind, müssen Sie sie `await`en („erwarten“).

    * E.g., `await myfile.seek(0)` navegaria para o ínicio do arquivo.
    * Isso é especialmente útil se você executar `await myfile.read()` uma vez e depois precisar ler os conteúdos do arquivo de novo.
* `close()`: Fecha o arquivo.

Como todos esses métodos são assíncronos (`async`) você precisa esperar ("await") por eles.
