-"""
-У нас есть класс FileHandler, который может считывать файлы, но не всегда в удобном для нас виде.
-Поэтому мы создали два его наследника: CSVHandler и JSONHandler
+'''Задания:
+    1. Переопределите метод is_available в классе AlcoholProduct с использованием super()
+    2. is_available у AlcoholProduct должен возвращать False если сейчас часы между 5 утра и 11 вечера.
+       Для определения текущего часа можно использовать datetime.now().hour
+    3. Создайте экземпляр класса AlcoholProduct и проверьте, можно ли сейчас продавать алкоголь.
+'''

-Задания:
-    1. Переопределите метод read у CSVHandler и JSONHandler
-    2. Метод read у JSONHandler должен возвращать словарь. Для этого используйте модуль встроенный модуль json
-    3. Метод read у CSVHandler должен возвращать список словарей. Для этого используйте модуль встроенный модуль csv
-    4. Создайте экземпляры каждого из трех классов.
-       С помощью экземпляра FileHandler прочитайте и распечатайте содержимое файла text.txt
-       С помощью экземпляра JSONHandler прочитайте и распечатайте содержимое файла recipes.json
-       С помощью экземпляра CSVHandler прочитайте и распечатайте содержимое файла user_info.csv
