What a class? A class is like a blueprint or template for creating objects. It defines the attributes (data) and methods (actions) that objects of that class will have. It is a logical entity and doesn't occupy memory space when declared.

What an object? An object is an instance of a class. It's a concrete entity that exists in memory and has specific values for the attributes defined by its class. It's a physical entity that can be manipulated.

A class is a blueprint for creating objects

Define a basic class

class Dog:
    def __init__(self, name, breed):
        self.name = name
        self.breed = breed
 
# Create an instance of the Dog class
my_dog = Dog("Buddy", "Golden Retriever")
 
# Access the attributes of the object
print(my_dog.name)
print(my_dog.breed)

You cannot print an object directly like a list, tuple, or dictionary

class Dog:
    def __init__(self, name, breed):
        self.name = name
        self.breed = breed
 
# Create an instance of the Dog class
my_dog = Dog("Buddy", "Golden Retriever")
 
# Access the attributes of the object
print(my_dog)

Instead, you print all values of an object with the _ _dict_ _ method

class Dog:
    def __init__(self, name, breed):
        self.name = name
        self.breed = breed
 
# Create an instance of the Dog class
my_dog = Dog("Buddy", "Golden Retriever")
print(my_dog.__dict__)
