sure! in python, object-oriented programming (oop) allows you to create classes that can have both class variables and object variables.

class variables are shared among all instances of a class, while object variables are unique to each instance. class variables are defined inside the class but outside of any methods, while object variables are typically defined within the `__init__` method.

here's an example to demonstrate class variables and object variables in python:

in this example:
`total_cars` is a class variable that keeps track of the total number of cars created.
`make` and `model` are object variables specific to each car instance.
the `__init__` method is used to initialize object variables when a new instance of the `car` class is created.
the `display_car_info` method is used to display the make and model of a car instance.
we create two car instances (`car1` and `car2`) and access their object variables using the `display_car_info` method.
we access the class variable `total_cars` to see how many cars have been created in total.

i hope this tutorial helps you understand class variables and object variables in python oop! let me know if you have any questions.
