# Implement a container class MyBox in the mybox.py file that stores and operates with the objects of the class developed by you in the task 8
# of the seminar tasks 1 (in the file myclass.py). Your container class needs to implement the following methods:
# - constructor method that initializes the container with some objects (more than one);
# - len() method that outputs the number of objects in the container ;
# - add(obj) method that adds a new object in the container;
# - remove(obj) method that removes the specified object from the container;
# - contains(obj) method that checks whether the specified object is in the container;
# - iterator() method that returns an iterator over the objects in the container;
