1. Basic Class and Object Creation

class Car:
    def __init__(self, model, color):
        self.model = model
        self.color = color

    def display_info(self):
        print(f'Model: {self.model}, Color: {self.color}')

car1 = Car("Toyota", "Red")
car1.display_info()

Model: Toyota, Color: Red

2. Class with Methods

class Circle:
    def __init__(self, radius):
        self.radius = radius

    def area(self):
        return 3.14 * self.radius ** 2

circle1 = Circle(5)
print("Area:", circle1.area())

Area: 78.5

3. Encapsulation (Private Attributes)

class Employee:
    def __init__(self, name, salary):
        self.__name = name
        self.__salary = salary

    def get_salary(self):
        return self.__salary

emp1 = Employee("John", 5000)
print(emp1.get_salary())

5000

4. Inheritance

class Animal:
    def sound(self):
        return "Some sound"…
