Example: How to find the largest of three numbers using multilevel inheritance in Python

class First:
    def __init__(self):
        self.num1 = int(input("Enter first number:"))
        self.num2 = int(input("Enter second number:"))
        self.num3 = int(input("Enter third number:"))
        self.large = 0


class Second(First):
    def check(self):
        if self.num1 > self.num2 and self.num1 > self.num3:
            self.large = self.num1
        elif self.num2 > self.num3:
            self.large = self.num2
        else:
            self.large = self.num3


class Third(Second):
    def result(self):
        print("Largest number is:", self.large)


obj = Third()
obj.check()
obj.result()

Output:

Enter first number:10
Enter second number:30
Enter third number:20
Largest number is: 30
