* `read(size)`: Читає `size` (`int`) байтів/символів з файлу.
* `seek(offset)`: Переміщується до позиції `offset` (`int`) у файлі.
    * Наприклад, `await myfile.seek(0)` поверне курсор на початок файлу.
    * This is especially useful if you run `await myfile.read()` once and then need to read the contents again. Це особливо корисно, якщо Ви виконуєте await `await myfile.read()` один раз, а потім потрібно знову прочитати вміст.
