Question regarding python code: Assignment: With inheritance in mind, create a class "Person" containing the instance variables name and social security number, as well as implementations of the methods __init__ and __str__. Then, create a subclass Motorist that inherits "Person" and adds the instance variable driver's license level (=B, C, etc). The __init__ and __str__ methods should be overridden appropriately. Finally, define a function/method that has Driving license that can distinguish objects of type Person and Motorist, without using "type" or "if.".
