Inheritance in Python

Inheritance allows one class (child) to inherit properties and methods from another class (parent). It promotes code reuse and organizes code logically.

Advantages of Inheritance

Code reusability
Improved structure and hierarchy
Easy maintenance and scalability

Example 1: Single Inheritance

class Employee:
    def show(self):
        print('Employee details')

class Manager(Employee):
    def display(self):
        print('Manager inherits Employee')

m = Manager()
m.show()
m.display()

Output:

Employee details
Manager inherits Employee

Example 2: Multilevel Inheritance

class Company:
    def company_info(self):
        print('Company: LiveCode')

class Employee(Company):
    def emp_info(self):
        print('Employee: Aryan')

class Manager(Employee):
    def mgr_info(self):
        print('Manager: Raj')

m = Manager()
m.company_info()
m.emp_info()
m.mgr_info()

Output:

Company: LiveCode
Employee: Aryan
Manager: Raj

Example 3: Hierarchical Inheritance

class Employee:
    def base(self):
        print('Base Employee')

class Developer(Employee):
    def dev(self):
        print('Developer Role')

class Tester(Employee):
    def test(self):
        print('Tester Role')

d = Developer()
t = Tester()
d.base()
d.dev()
t.base()
t.test()

Output:

Base Employee
Developer Role
Base Employee
Tester Role

Example 4: Multiple Inheritance

class A:
    def methodA(self):
        print('From Class A')

class B:
    def methodB(self):
        print('From Class B')

class C(A, B):
    def methodC(self):
        print('From Class C')

obj = C()
obj.methodA()
obj.methodB()
obj.methodC()

Output:

From Class A
From Class B
From Class C
