Паттерн Декоратор — специальный способ организации модулей в программе, который позволяет подставить какую-то новую функцию прямо в середину цепочки вызовов, тем самым чуть-чуть подкорректировав поведение.
Например, в реальном мире очки для чтения это декоратор. Вы ставите их между вашими глазами и текстом. Глобально взаимодействие ваших глаз и текста не меняется: отражённые световые лучи от страницы книги попадают в ваши зрачки, что с очками, что без них. Но очки располагаются посередине: они принимают лучи на вход и преломляют их, передавая дальше вам в глаза уже изменёнными.
Важной особенностью является тот факт, что очки можно снять. Они не требуют ни модификации вашего тела, ни модификации книги. Вообще никакие условия не нужны, кроме наличия самих очков. А если вы в линзах, то внешний наблюдатель может даже этого не знать.
Класс-декоратор должен быть спроектирован так, чтобы не требовать никаких изменений в объектах, с которыми он работает. Его можно отключить, чаще всего буквально закомментировав одну строку.
В примере ниже программа выведет текст "Привет, мир, в натуре.", и вот это дополнение в конце как раз дописано декоратором. Можно убрать или закомментировать подчёркнутую строчку, не трогая остальной код, для всех внешних вызовов сигнатуры останутся теми же самыми, но выводиться будет уже просто "Привет, мир".
В декораторы можно прятать логику, которую буквально навешивают поверх основной функции программы. Например, проверку прав на выполнение операции. Перевод на другой язык, логирование, поддержку обратной совместимости при обновлении и так далее.
