"""
__init__ Method: This is the initializer method that sets up an instance of the MyNumber class with a given value. When you create an instance of MyNumber, you pass a value to it, and this value is stored in the value attribute of the instance.
__eq__ Method: Checks if the other object is an instance of MyNumber. If it is, it compares their value attributes for equality. If other is not an instance of MyNumber, it returns NotImplemented.
