 SOME OBJECT ORIENTED PROGRAMMING QUESTIONS IN PYHTON FOR ENGINEERING STUDENTS.

1. Question: Create a class named Rectangle with two attributes width and height. Create a method named area which will calculate the area of the rectangle. Create a method named perimeter which will calculate the perimeter of the rectangle. Create an object of the Rectangle class and print its area and perimeter.

Answer:

python
class Rectangle:
    def __init__(self, width, height):
        self.width = width
        self.height = height

    def area(self):
        return self.width * self.height

    def perimeter(self):
        return 2 * (self.width + self.height)

# Creating an object of Rectangle class
rect = Rectangle(5, 10)

# Printing area and perimeter of the rectangle
print("Area:", rect.area())
print("Perimeter:", rect.perimeter())

Output:

Area: 50 Perimeter: 30

2. Question: Create a class named BankAccount with two attributes balance and owner_name. Create a method named deposit which will add an amount to the balance. Create a method named withdraw which will subtract an amount from the balance. If the withdrawal amount is greater than the balance, print "Insufficient balance". Create an object of the BankAccount class and perform some transactions.

Answer:

python
class BankAccount:
    def __init__(self, owner_name, balance=0):
        self.owner_name = owner_name
        self.balance = balance

    def deposit(self, amount):
        self.balance += amount

    def withdraw(self, amount):
        if amount > self.balance:
            print("Insufficient balance")
        else:
            self.balance -= amount

# Creating an object of BankAccount class
acct = BankAccount("John")

# Depositing some money
acct.deposit(1000)

# Withdrawing some money
acct.withdraw(500)

# Trying to withdraw more than the balance
acct.withdraw(10000)

# Printing the balance
print("Balance:", acct.balance)

Output:

Insufficient balance Balance: 500

3. Question: Create a class named Person with two attributes name and age. Create a method named display which will print the name and age of the person. Create a class named Student which inherits from the Person class and has an additional attribute roll_no. Override the display method of the Person class in the Student class to print the name, age, and roll number of the student. Create an object of the Student class and call its display method.

Answer:

python
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def display(self):
        print("Name:", self.name)
        print("Age:", self.age)

class Student(Person):
    def __init__(self, name, age, roll_no):
        super().__init__(name, age)
        self.roll_no = roll_no

    def display(self):
        super().display()
        print("Roll No:", self.roll_no)

# Creating an object of Student class
student = Student("John", 20, 1234)

# Calling the display method of Student class
student.display()

Output:

Name: John
Age: 20
Roll No: 1234
