Using multiple inheritance

Multiple inheritance is where one class inherits two or more classes, as shown in the following diagram:

Class C inherits both classes, class A and class B.

The following statement defines multilevel inheritance where the Result class inherits the Marks class and the Marks class in turn inherits the Student class:

class Student:
    class Marks:
        class Result(Student, Marks):

In the preceding statements, Student and Marks are the base classes and the Result class inherits both the Student class and the Marks class. Consequently, the instance of the Result class can access the methods and variables of the Marks and Student classes.

Getting ready

To understand the concept of multilevel inheritance practically, let's create an application that will prompt the user to enter the code, name, history marks, and geography marks of a student, and will display the total marks and percentage on the click of a button. The total marks will be the sum of history marks and geography...
