Is inheritnace the only option

[QueenSvetlana]

inheritance would make sense here.

return "ID: " + self.iden + " " + " First: " + self.first_name + " Last Name: " + self.last_name + " " + " Type: " + self.student_type

'

return "ID: {} First: {} Last Name: {} Type: {}".format(self.iden, self.first_name, self.last_name, self.student_type)

Thanks for the help. Have I implementation my abstract class properly?

you can get rid of the private variables as well as the getters and setters. If you need the class variables, just use them.

Why not use the getters/setter?
