Defining the __str__ method in a class is what we call operator overloading -- Python will convert any object to a string with the str() method by default, but it may not always be what we want. By defining the __str__ method, we can overwrite Python's default behavior to behavior that we want. However, when we call the overloaded method on an instance of the class, we do not need the dunders, we can just say str(object_instance)
Suggested change
| return self.store.__str__() | |
| return str(self.store) |
