Принимает строку, число, дату или дату-с-временем. Возвращает строку, содержащую шестнадцатеричное представление аргумента. Используются заглавные буквы A-F. Не используются префиксы 0x и суффиксы h. Для строк просто все байты кодируются в виде двух шестнадцатеричных цифр. Числа выводятся в big endian ("человеческом") формате. Для чисел вырезаются старшие нули, но только по целым байтам. Например, hex(1) = '01'. Даты кодируются как число дней с начала unix-эпохи. Даты-с-временем кодируются как число секунд с начала unix-эпохи.

Принимает строку, содержащую произвольное количество шестнадцатеричных цифр, и возвращает строку, содержащую соответствующие байты. Поддерживаются как строчные, так и заглавные буквы A-F. Число шестнадцатеричных цифр не обязано быть чётным. Если оно нечётное - последняя цифра интерпретируется как младшая половинка байта 00-0F. Если строка-аргумент содержит что-либо кроме шестнадцатеричных цифр, то будет возвращён какой-либо implementation-defined результат (не кидается исключение).
Если вы хотите преобразовать результат в число, то вы можете использовать функции reverse и reinterpretAsType.
