This is for one of my assignments for my intro programming class and believe I have done this correctly. We just started classes and object orienting programming. Could someone clarify that this is done correctly? I'm mainly wondering about the part of the inheritance of classes.

-Assignment
-Create a Person class that provides attributes for first name, last name, and email address. This
class should provide a property or method that returns the person's full name.
-Create a Customer class that inherits the Person class. This class should add an attribute for a
customer number.
-Create an Employee class that inherits the Person class. This class should add an attribute for a
social security number (SSN).
-The program should create a Customer or Employee object from the data entered by the user, and
it should use this object to display the data to the user. To do that, the program can use the
isinstance() function to check whether an object is a Customer or Employee object.


-And this is my code. If there are any corrections that you can think of, could you please tell me?
Thanks!

Think you're going to have to embed your code before anyone even reads that!

at a quick glance you're recreating methods from parent classes which defeats the purpose of inheritance.


class Person:
    def get_first(self):
        return self.first

class Employee(Person):
    def get_first(self):
        return self.first


The employee method is unnecessary as its inherited from Person
