Class vs Instance Attributes

Class attributes are shared by all instances:

class Dog:
    species = "Canis familiaris"  # Class attribute
    
    def __init__(self, name):
        self.name = name  # Instance attribute
dog1 = Dog("Buddy")
dog2 = Dog("Max")
print(dog1.species)  # Same for all dogs
print(dog2.species)  # Same value

Your Task

• Class attribute currency = "USD"
• Instance attributes: description, amount
