1. State the use of inheritance
Inheritance is a key Object-Oriented Programming (OOP) concept that allows a class to
inherit properties and methods from another class. It helps in code reusability, modularity, and
maintaining hierarchy in a program.
Main Uses of Inheritance:
1. Code Reusability:
o Common attributes and methods are defined in a base class and reused in derived
classes, reducing code duplication.
2. Method Overriding:
o A subclass can redefine a method from the parent class to provide specialized
behavior.
3. Extensibility:
o New functionalities can be added to existing classes without modifying their code.
4. Data Abstraction and Encapsulation:
o Inheritance helps implement abstraction by creating a base class with generalized
features and extending it for specific use cases.
5. Hierarchical Structure:
o It helps in creating a structured and organized program by defining relationships
between classes.
2. List different types of inheritance
Types of Inheritance in Python
1. Single Inheritance: A subclass inherits from a single parent class.
Example:
class Animal:
def sound(self):
print("Animals make sounds.")

Programming with ‘Python’ Practical: 15 Lab Manual (Solved)
class Dog(Animal):
def sound(self):
print("Dog barks.")
d = Dog()
d.sound() # Output: Dog barks.
2. Multiple Inheritance: A subclass inherits from multiple parent classes.
3. Multilevel Inheritance: A subclass inherits from another subclass, forming a chain.
4. Hierarchical Inheritance: Multiple subclasses inherit from a single parent class.
5. Hybrid Inheritance: A combination of two or more types of inheritance.
1. Create a class Employee with data members: name, department and salary. Create suitable
methods for reading and printing employee information
class Employee:
def __init__(self, name, department, salary):
self.name = name
self.department = department
self.salary = salary
def display(self):
print("Employee Name:", self.name)
print("Department:", self.department)
print("Salary:", self.salary)
# Creating an Employee object
emp = Employee("Rashid", "IT", 50000)
# Displaying employee details
emp.display()
2. Python program to read and print students information using two classes using simple
inheritance.
class Person:
def __init__(self, name, age):
self.name = name
Jamia Polytechnic Akkalkuwa Page No:02 Prepared by: Sayyed Waliullah
Programming with ‘Python’ Practical: 15 Lab Manual (Solved)
self.age = age
def display(self):
print("Name:", self.name)
print("Age:", self.age)
class Student(Person):
def __init__(self, name, age, course):
super().__init__(name, age)
self.course = course
def display(self):
super().display()
print("Course:", self.course)
# Creating a Student object
s = Student("Zaid", 20, "Computer Science")
# Displaying student details
s.display()
3. Write a Python program to implement multiple inheritance
class Father: class Teacher:
def show_father(self): def teach(self):
print("I am the Father.") print("I teach students.")
class Mother: class Researcher:
def show_mother(self): def research(self):
print("I am the Mother.") print("I conduct research.")
class Child(Father, Mother): class Professor(Teacher, Researcher):
def show_child(self): def guide(self):
print("I am the Child.") print("I guide students and researchers.")
# Creating an object of Child class # Creating an object of Professor
c = Child() prof = Professor()
# Calling methods from both parent classes
c.show_father() # Calling methods from both parent classes
c.show_mother() prof.teach() # From Teacher class
c.show_child() prof.research() # From Researcher class
prof.guide() # From Professor class
Write Any one Example but perform both
