What is the purpose of an object in Python OOP?

a) To store multiple functions in a variable

b) To represent an instance of a class with specific attributes and behaviors

c) To execute a loop

d) To perform mathematical calculations

Answer:

b) To represent an instance of a class with specific attributes and behaviors

Explanation:

An object in Python OOP is an instance of a class, representing a specific entity with defined attributes (data) and behaviors (methods). Objects are the fundamental building blocks of an OOP-based program, allowing you to model real-world entities and their interactions.

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

    def start_engine(self):
        print(f"The engine of the {self.brand} {self.model} is now running.")

# Creating an object of the Car class
my_car = Car("Toyota", "Corolla")
my_car.start_engine()  # Output: The engine of the Toyota Corolla is now running.

In this example, the my_car object is an instance of the Car class, representing a specific car with a brand and model. The object can perform actions defined by its methods, such as starting the engine.

Objects provide a way to organize data and behavior in a structured and reusable manner, making it easier to model complex systems and processes in code.
