Теперь запакуем строку. В этом случае следует передавать тип данных bytes. >>> struct.pack('=s', b'a') b'a' Для записи слова следует указывать количество символов. >>> struct.pack('=5s', b'hello') b'hello' Кстати, запакованный вид соответствует исходному тексту. Всё верно, символ есть в таблице ASCII, то есть его код попадает в диапазон 0-127, он может быть записан одним байтом и имеет визуальное представление. А вот что будет если добавить символ вне ASCII >>> struct.pack(f'=s', b'ё') SyntaxError: bytes can only contain ASCII literal characters. Ошибка возникла еще на этапе создания объекта bytes, который не может содержать такой символ. Поэтому надо кодировать эти байты из строки. >>> enc = 'ёжик'.encode('utf-8') >>> struct.pack(f'={len(enc)}s', enc) b'\xd1\x91\xd0\xb6\xd0\xb8\xd0\xba' Заметьте, длина такой строки в байтах отличается от исходной длины, так как символы вне ASCII записываются двумя байтами и более. Поэтому здесь формат создаём на лету, используя получившуюся длину как каунтер токена. #libs#basic
