How do I use class variables in Python?

Can you explain how to use class variables in Python?

Sure! Class variables are shared among all instances of a class. They are defined within the class but outside any instance methods.

How do I define a class variable?

You define a class variable by assigning a value to a variable inside the class definition, like this: class MyClass: followed by my_variable = 0.

Can you give me an example of using class variables?

Absolutely! Here's a simple example: class Counter: with a class variable count = 0. Each time you create an instance, you can increment Counter.count.

What happens if I change the class variable from an instance?

If you change the class variable from an instance, it will change for all instances unless you override it in that specific instance.
