What are some examples of class attributes in Python?

Class attributes in Python are variables that are shared among all instances of a class. For example, in a class Car, you might have a class attribute wheels set to 4.

Can you show me a code example?

Sure! Here's a simple example:

class Car:
    wheels = 4  # class attribute

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

my_car = Car('red')
print(my_car.wheels)  # Output: 4

What happens if I change the class attribute?

If you change the class attribute, it will affect all instances of the class. For example:

Car.wheels = 5
print(my_car.wheels)  # Output: 5

Are there any differences between class attributes and instance attributes?

Yes, class attributes are shared across all instances, while instance attributes are unique to each instance. Changing an instance attribute does not affect the class attribute.
