All updations for deleted values and assignment of attributes change the instance dictionary and not the actual class. The__setattr__method is called directly to update the instance dictionary if it has been set in this case. The problem arises if you use the following syntax:self.name = val...

The class variable in Python can be accessed with an object by using the dot notation object_name.attribute_name. This will help you to retrieve the value of the class attribute that is associated with the specific object. As the class attributes are shared among all the objects, accessin...
