OOP 3: Initializing
3.1. Add an __init__() function to the Car class that takes the brand and model arguments and assigns them to the appropriate object attributes.
3.2. You already have an object my_car that was created without passing additional arguments. So, in order not to cause errors when creating an object in this way, let's add a default value for the arguments of the __init__() function They mast have values of empty string "".
3.3. Create two new Car objects by passing the following string values as arguments. some_car1: brand - Ford, model - Mustang; some_car2: model - Camaro. Notice, that the second car has only model, it's brand must remains default.
