In object-oriented programming (OOP), an object is an instance of a class. It has its own state (data) and behavior (methods).
An object is created from a class, and it is a self-contained entity that contains the data and logic needed to represent a specific entity or concept. Objects are often used to model real-world entities, such as a person, a place, or a thing.
Here is an example of an object in Python:
class Dog:
def __init__(self, name, breed):
self.name = name
self.breed = breed
def bark(self):
return "Woof!"
dog1 = Dog("Fido", "Labrador")
In this example, the Dog
class is a template or blueprint for creating Dog
objects. The dog1
object is an instance of the Dog
class, and it has its own name
and breed
attributes and a bark
method.
You can access the attributes and call the methods of an object using the dot notation:
print(dog1.name) # "Fido"
print(dog1.breed) # "Labrador"
print(dog1.bark()) # "Woof!"
Objects are a fundamental concept in OOP, and they are used to represent real-world entities and concepts in a program. They allow you to model complex systems by breaking them down into smaller, more manageable parts.
