What are class attributes in Python?

What are class attributes in Python?

Class attributes are variables that are shared across all instances of a class. They are defined within the class but outside any instance methods.

Can you give me an example of a class attribute?

Sure! Here's a simple example:

class Dog:
    species = "Canis familiaris"  # class attribute

    def __init__(self, name):
        self.name = name  # instance attribute

my_dog = Dog("Buddy")
print(my_dog.species)  # Output: Canis familiaris

How do class attributes differ from instance attributes?

Class attributes are shared by all instances of the class, while instance attributes are unique to each instance.

Can class attributes be modified?

Yes, class attributes can be modified, but doing so will change the value for all instances that share that attribute.
