Multilevel Inheritance in Python

class Base:
    # Constructor to set Data
    def __init__(self, name, roll, role):
        self.name = name
        self.roll = roll
        self.role = role

# Intermediate Class: Inherits the Base Class
class Intermediate(Base):
    # Constructor to set age
    def __init__(self, age, name, roll, role):
        super().__init__(name, roll, role)
        self.age = age

# Derived Class: Inherits the Intermediate Class
class Derived(Intermediate):
    # Method to Print Data
    def __init__(self, age, name, roll, role):
        super().__init__(age, name, roll, role)

    def Print_Data(self):
        print(f"The Name is : {self.name}")
        print(f"The Age is : {self.age}")
        print(f"The role is : {self.role}")
        print(f"The Roll is : {self.roll}")

# Creating Object of Base Class
obj = Derived(21, "Lokesh Singh", 25, "Software Trainer")

# Printing the data with the help of derived class
obj.Print_Data()

class Shape:
    def area(self):
        raise NotImplementedError("Subclasses must Implement area()")


class Rectangle(Shape):

        self.width = width
        self.length = length

    def area(self):
